The activation energy for the reaction 2HI (g) H2(g) + 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.

Answer:

Fraction of molecules having energy equal to greater than activation energy,   Thus, = ?18.8323 = x = antilog () = 1.47 × 10?19.
