True or False : Higher the activation energy of a reaction, faster is the reaction.

Define activation energy of a reaction.

The activation energy of reaction is equal to

The activation energy of a reaction can be determined by

The activation energy for the reaction if k = A is

Each question contains STATEMENTS-1 (Assertion) and STATEMENT -2 (Reason). Examine the statements carefully and mark the correct answer according to the instructions given below: STATEMENT -1: If the activation energy of reaction is zero, temperature will have no effect on the rate constant. STATEMENT-2: Lower the activation energy faster is the raction.

What is activation energy? How is related to rate constant of a reaction?

True or False Enzymes act by lowering the activation energy.

True or False : Selectivity is the ability of a catalyst to direct the reaction to give a particular product.

True or False The lower the frequency of vibration, the higher is the pitch.
