Question

The energy of activation for the reaction 2H202— 2H,O+O,
in absence of catalyst is 75 K.Jmole".
The most likely value for the energy of activation in presence of catalyst
is: (A) 53 K.Jmole' XB) 75 K.Jmole' (C) 98 K.Jmole!


Answer is B
but Energy decreases in presence of cataylyst??

Answer 1

Yes is are right the answer must be a and not b

The presence of a catalyst decreases the activation energy

I hope this helps ( ╹▽╹ )
