39
In the equation q = nCΔT, what do the variables stand for? Answer…
40
q = energy as heat n = number of moles C = molar heat capacity ΔT = change in temperature 200
41

46
-1,637 kJ 500
47
Explain the difference between heat and temperature. Answer…
48
Heat: the energy transferred between objects that are at different temperatures Temperature: a measure of the average kinetic energy of the particles in a sample of matter OR a measure of how hot or cold something is 100
49
How is molar heat capacity related to specific heat? Answer…
50
Molar Heat Capacity: energy needed to raise the temperature of 1 mole of a substance by 1K Specific Heat: energy needed to raise the temperature of 1 gram of a substance by 1K OR (molar mass) (specific heat) = molar heat capacity 200
51
How is a change in Gibbs energy related to changes in enthalpy and entropy? Answer…
52
ΔG = ΔH - TΔS 300
53
Explain why the effects of entropy increase as temperature increases. Answer…
54
G = H - TS As the temperature increases, the kinetic energy of the particles also increases, contributing to more disorder in the system. Also, as T increases, S is being multiplied by an even bigger number, increasing the effects of entropy even further. 400
55
How do the signs (+ or -) of ΔH and ΔS predict the spontaneity of a reaction? Answer…
56
- ΔH and +ΔS = spontaneous +ΔH and -ΔS = non-spontaneous 500
