Alreay ANswered this qstn.plz do check your previous one.Reposting it for the ease:From the activation energy formulae:At temperature 400 K, the time constant is with Ea activation energy,
K = Z*e^(-Ea/400R)............(1)
and
after decreasing we get,
At temperature 300 K, the time constant is with Ea activation energy,
k = ze^(-0.05xEa/300R)..................(2)
Solving both the eqns. we get,
0.05x = 0.75
or
x = 15.
