Reaction Rates Popcorn Activity

Step 1 Count how many pieces of popcorn you have Record how many pieces of popcorn were eaten every 20 seconds for 5 min Create a graph of pieces of popcorn left vs. time This is the idea of concentration vs. time

Why are some collisions effective and others not? Orientation How fast they hit

For A products r=-k[A] For A + B  products K is the reaction constant r is the rate of reaction (moles or Molarity decreasing over unit time) A is the concentration or quantity of reactant For A + B  products r= - k [A]m[B]n m and n refer to how reactant A and B concentration change the rate

Overall reaction order A certain rate law is given as Rate=k[H2]1[Br2]1/2 What is the reaction order? x=1,y=1/2 Reaction order=x + y =1+1/2=3/2 The reaction is first-order in hydrogen, one-half-order in bromine, and 3/2-order overall.
