Question

The rate of chemical reaction becomes double for every 10° rise in temperature because of ____________.

Options

• increase in activation energy

• decrease in activation energy

• increase in number of collisions between molecules having energy greater than activation energy

• increase in number of activated molecules

Answer 1

The rate of chemical reaction becomes double for every 10° rise in temperature because of increase in number of collisions between molecules having energy greater than activation energy.

Explanation:

With the increase in temperature molecular collisions increases therefore the rate of reaction doubles. With every 10° rise in temperature, the number of molecules which bring about the chemical reaction becomes double, so the rate of chemical reaction also double.
