How is the rate of a reaction affected by the presence of catalyst ?

For a reaction A+BrarrP , the rate is given by Rate =k[A][B]^(2) How is the rate of reaction affected if the concentration of B is doubled ?

A reaction is second order with respect to a reactant . How is the rate of reaction affected if the concentration of the reactant is reduced to half ?

A reaction is second order with respect to a reactant . How is the rate of reaction affected if the concentration of the reactant is doubled

How does enthalpy of a reaction remain unaltered in the presence of a catalyst, explain.

The activation energy of a reaction is 80"kj.mol"^(-1) . The activation energy reduces by 75% in presence of a catalyst. If the other parameters are kept constant , compare the rates of the reaction in presence and absence of the catalyst at 25^(@)C .

How is activation energy affected by the use of a catalyst.

If the change in enthalpy of a reaction in absence of a catalyst is "xkJ.mol"^(-1) what will be the change in enthalpy of the reaction in the presence of a catalyst?

A hydrogenation reaction is carried out at 500K.If the same reaction is carried out in the presence of a catalyst at the same rate temperature required is 400K. Calculate the activation energy of the reaction if the catalyst lowers the activation barrier by 20"kJ.mol"^(-1)

At a given temperature , for a reaction , the activation energy in absence of catalyst is greater than that in presence of catalyst be an amount of RT. If the value of the rate constant in presence of catalyst is x times that in absence of catalyst, then find the value of x.
