In general, reaction rates double when the temperature is increased by 10ºC. The temperature of a reaction is increased by 40ºC. The rate of the reaction will increase by a factor of ____? is it 16?

Answer 1

r = k*2^n.
k = initial reaction rate.
r = reaction rate after temperature
change.

40deg. / 10deg. = 4.
r = k*2^4 = 16k = 16 times initial temp.
