Question

$I$. An endothermic reaction process cannot occur spontaneously.
$II$. The enthalpy change for an endothermic process is negative.

• A. Statement $I$ is true, Statement $II$ is true
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

The correct option is D Statement $I$ is false, Statement $II$ is false

An endothermic process can never be spontaneous if $△S=$ positive whereas if $△S$ is positive, reaction can be spontaneous at high temperature.

Also, $△H$ for an endothermic process is positive.
