What is catalyst ? How does the phenomenon of adsorption explain the role played by catalyst ?

(A) Positive catalyst increases the rate of reaction (R) Catalyst decrease the value of DeltaG^(@)

Write down the name of catalyst for the following: Adams catalyst in reduction.

(A)Catalyst increases the rate of reaction. (R ) Catalyst functions by lowering the energy of activation.

Wilkinson's catalyst is used as a homogeneous hydrogenation catalyst for the conversion of alkenes to alkanes. It is a complex of
