(a) The activation energy for the isomerization of methyl isonitrile (see figure) is 160 kJ/mol. Calculate the fraction of methyl isonitrile molecules that has an energy of 160.0 kJ or greater at 493 K.
(b) Calculate this fraction for a temperature of 532 K.
What is the ratio of the fraction at 532 K to that at 493 K?
