Problem  63E

Temperature and Rate (Section)

(a) A certain first-order reaction has a rate constant of 2.75 × 10-2 s-1 at 20 °C. What is the value of k at 60 °C if Ea = 75.5 kJ/mol ? (b) Another first-order reaction also has a rate constant of 2.75 × 10-2 s-1 at 20 °C What is the value of k at 60 °C if Ea = 125 kJ/mol ? (c) What assumptions do you need to make in order to calculate answers for parts (a) and (b)?
