Higher the activation energy of a reaction slower is the rate of the reaction Explain.

Define activation energy of a reaction.

What is the rate of a reaction?

The rate of a chemical reaction.

The activation energy of a reaction is 75.2 KJ mol^-1 in the absence of a catalyst and 50.14 Kjmol^-1 with a catalyst. How many times will the rate of reaction grow in the presence of the catalyst if the reaction proceeds at 25^@C ? (R = 8.314 JK^-1mol^-1)

Why is respiration considered an exothermic reaction? Explain.

Define nuclear chain reaction. Explain.
