Two reaction : X rarr Products and Y rarr Products have rate constants k_(1) and k_(2) at temperature T and activation energies E_(1) and E_(2) , respectively. If k_(1) gt k_(2) and E_(1) lt E_(2) (assuming that the Arrhenius factor is same for both the Products), then (I) On increaisng the temperature, increase in k_(2) will be greater than increaisng in k_(1) . (II) On increaisng the temperature, increase in k_(1) will be greater than increase in k_(2) . (III) At higher temperature, k_(1) will be closer to k_(2) . (IV) At lower temperature, k_(1) lt k_(2)

The rate of reaction increases isgnificantly with increase in temperature. Generally, rate of reactions are doubled for every 10^(@)C rise in temperature. Temperature coefficient gives us an idea about the change in the rate of a reaction for every 10^(@)C change in temperature. "Temperature coefficient" (mu) = ("Rate constant of" (T + 10)^(@)C)/("Rate constant at" T^(@)C) Arrhenius gave an equation which describes aret constant k as a function of temperature k = Ae^(-E_(a)//RT) where k is the rate constant, A is the frequency factor or pre-exponential factor, E_(a) is the activation energy, T is the temperature in kelvin, R is the universal gas constant. Equation when expressed in logarithmic form becomes log k = log A - (E_(a))/(2.303 RT) For the given reactions, following data is given {:(PrarrQ,,,,k_(1) =10^(15)exp((-2000)/(T))),(CrarrD,,,,k_(2) = 10^(14)exp((-1000)/(T))):} Temperature at which k_(1) = k_(2) is
