Question

The activation energy of a first order reaction at 300 K is 60 KJ/mol. In the presence of a

catalyst, the activation energy gets lowered to 50 KJ /mol at 300K. how many times the

reaction rate changes in the presence of a catalyst at the same temperature.​

Answer 1

Answer:

the activation energy in kJ/mol for a first order reaction if its specific rate constant 3.00e-05 s-1 at 350. K and 2.04e+02 s-1 at 510. K Ea= An Arrhenius plot (ln k vs. 1/T) for a second order reaction (2A -> C) produced a straight line with a slope of -7.20e+03 K.
