Question

In an exothermic reaction if $\Delta H$ is the enthalpy, then activation energy is:

• A. more than $\Delta H$
• B. less than $\Delta H$
• C. equal to $\Delta H$
• D. none of the above

Answer 1

The correct option is A more than $\Delta H$

(A) more than $△H$

because activation energy

must be highest than the

$△H$ value to activate it.
