For a first order reaction A P, the temperature (T) dependent rate constant (k) was found to follow the equation 1 logk 6.0 T . The pre- exponential factor A and the activation energy Ea, respectively are: (a) 1.0 10 s and 9.2 kJ mol x (b) 6.0s and 16.6 kJ mol (c) 1.0 10 s and 16.6 kJ mol x (d) 1.0 10 s and 38.3 kJ mol x
