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

For the two gaseous reactions, following data are given A rarr B, k_(1) =10^(10) e^(-20,000//T), C rarr D, k_(2) =10^(12) e^(-24,606//T) the temperature at which k_(1) becomes equal to k_(2) is :

The rate constant k_(1) and k_(2) for two different reactions are 10^(16) e^(-2000//T) and 10^(15) e^(-1000//T) , respectively. The temperature at which k_(1) = k_(2) is
