11 . The activation energy for the reaction 2HI(g)----> H2(g) + I2(g) is 209.5 kJ mol -1 at 581 K. The fraction of molecules of reactants having energy equal to or greater than activation energy would be , (A) 1.462 x 10-19 (B) 1.462 x 1028 (C) 1.462 x 1024 (D) 1.462 x 1034 I hv no idea to this aieee problem from kinetics........kindly help me...
