Kinetics - A2

Question 1

rate = k{E}

explain qualitatively why doubling the temp has a much greater effect on the ror than doubling the conc of E

Answer 1

reaction occurs when molecules have at least the minimum Ea
doubling the temp by 10*C causes many more molecules to have this required energy
while doubling the conc of E only doubles the number with this energy

Question 2

state effect on K value when temp is lowered but all other conditions kept constant + why

Answer 2

will decrease

because fewer particles have sufficient ea to react
