The activation energy for the reaction 2HI(g) → H2 + I2(g) is 209.5 kJ mol-1 at 581 K. Calculate the fraction of molecules of reactants having energy equal to or greater than activation energy?
In the given case:
Ea = 209.5 kJ mol - 1 = 209500 J mol - 1
T = 581 K
R = 8.314 JK - 1 mol - 1
Now, the fraction of molecules of reactants having energy equal to or greater than activation energy is given as
