If a homogeneous catalytic reaction can take place through three alternative paths as depicted below, the catalytic efficiency of P, Q, R representing the relative case would be

Answer»

<P> PgtQgtR
QgtPgtR
PgtRgtQ
RgtQgtP

Solution :The catalytic efficiency of a CATALYST is measured in terms of the decrease in ACTIVATION energy of the reaction. A catalyst is more efficient if it decreases the `E_a`, to a larger extent. Thus, CORRECT order for catalytic efficiency is R>Q>P.
