Hydrogenation reaction is carried out at 500 K. If the same reaction is carried out in the presence of catalyst at the same rate, the temperature is 400K. Calculate the activation energy if catalyst lowers the activation energy by\[20\text{ }KJ/mol\]:-

A)  \[100\text{ }KJ/mol\]    

B)  \[50\text{ }KJ/mol\]

C)  \[30\text{ }KJ/mol\]     

D)  \[20\text{ }KJ/mol\]
