A series of experiments were conducted to measure the rate of a reaction at different temperatures. Which of the following statements is correct?
a. The gradient of a graph of rate against temperature in kelvin would equal the activation energy.
b. The gradient of a graph of ln rate against temperature in kelvin would equal the activation energy.
c. The gradient of a graph of ln rate against 1/T (in kelvin) would equal the activation energy.
d. The gradient of a graph of ln rate against 1/T (in kelvin) would equal R−Ea .
