Rate Of Reaction Concept Rate of reaction defined as : Change of concentration of reactant or result of reaction of every one set of time Concentration applied is molarity ( M) or mole per litre ( mole. L⁻¹) Set of time could be in the form of second, minute, hour(clock, day or year but used occasionally second So rate of reaction has set of mole per litre per second ( mole. L⁻¹.s⁻¹ or Ms⁻¹) Along with increasing of reaction time, hence reactant matter amounts would fewer, while product more and more many, so that : Rate of reaction expressed as speed of the lessen of reactant or fast increasing of product.

Isi dengan Judul Halaman Terkait Continuation Rate of reaction picture A becomes B, shown with the lessen of molecule A and increasing of molecule B in one set of time. Hal.: 5 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Continuation Graph is upper able to be written as equation reaction of as follows : a A → b B V = - d( A ) = + d( B ) t t Minus sign (-) shows concentration of reactant more and more decreases Positive sign (+) shows concentration of product more and more increases Hal.: 6 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait The Hammering Theory Theoritical of hammering reaction of taking place as result of hammering between reactant particles Not every hammering yields reaction, but only hammering between effective particles Only having enough energy and direction of correct hammering yielding reaction Conditions the happening of a reaction : 1. Effective hammering, that is hammering yielding reaction If reactant molecule moving direction, stands a chance is big there will be hammering one another, either with the same molecule and also differs in the conclusive. Hammering of tying in reactant molecule and then forms new tying which yields molecule result of reaction. Hal.: 7 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Continuation 2. Hammering Energy that is Enough Minimum energy which must be owned by reactant particle causing yields effective hammering called as energy activation ( Ea = activation energy) Hammering with energy that is conclusive enough of tying and forming of new tying Hal.: 8 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Continuation exothermic activation energy endothermic activation energy Hal.: 9 Isi dengan Judul Halaman Terkait

Factor Influencing Rate of reaction Temperature Excelsior temperatur,makin kinetik head , movement of molecule more and more quickly so that opportunity the happening of hammering would be more and reaction of taking place is quicker Concentration Of More and more big concentration , number of molecules more and more many , more and more big opportunities the happening of hammering and reaction of more and more quickly Pengadukan / mechanic Waters down event of hammering between molecules causing reaction easy to happened. Matter surface area More and more matter surface area more and more many opportunities the happening of hammering causing reaction of taking place is quicker Catalyst existence of a matter which when interaction with reaktan will give new line which its(the activation energy lower than initialy, causing quicker reaction happened.

Rate Equation of Reaction To react : a A + b B → c C + d D applies reaction rate law = k [A]m [B]n With : k = rate constant, influenced temperature and catalyst ( if is exist) m = order ( storey) reaction of to reactant A nitrogen = order ( storey) reaction of to reactant B [ A], [ B] = concentration of in molarity Rank m and n determined from experiment data Ever greater the price of k reaction of will take place is quicker Increase of temperature and usage of catalyst generally enlarges the price of k Hal.: 11 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Reaction Order Determines order reaction of is one of way of approximating how far concentration of reactant matter influences certain rate of reaction Order reaction or order of reaction to a component is rank from concentration of the component in reaction rate law Example : v = k [A]m [B]n M= order reaction of to A n = order reaction of to B Orde total = m + n change of concentration of is a, and change of rate of reaction is b hence applying : ax= b Hal.: 12 Isi dengan Judul Halaman Terkait
