# Problem: The activation energy for the isomerization of methyl isonitrile  is 160 kJ/mol.Calculate the fraction of methyl isonitrile molecules that have an energy of 160.0 kJ or greater at 501 K .

###### FREE Expert Solution

Recall that the Arrhenius equation can be written as

k = rate constant

Ea = activation energy (in J/mol)

R = gas constant (8.314 J/mol • K)

T = temperature (in K)

A = Arrhenius constant or frequency factor
