the activation energy of a reaction is 75.2kj/mol in the absence of a catalyst and 50.14kj/mol with a catalyst.how many times will the rate of reaction grow in the presence of the catalyst if the reaction preceeds at 25degree celcius?

Expert Answer:
According to A rrhenius equation,
Let for uncatalysed reaction ,
--------(i)
And , for catalysed reaction ,
---------(ii)
Subtracting equation (i) from equation (ii)
=
= 4.39
Taking antilog on both sides,we have
Therefore rate of reaction increased by 2.45 x 104 times
