Question

Selection of temperature to carry out a reduction process depends so as to make:

• A. $\Delta G$ = negative
• B. $\Delta G$ = positive
• C. $\Delta G$ = zero
• D. $\Delta H$ = positive

Answer 1

The correct option is A $\Delta G$ = negative

In general when $\Delta G$ is negative, any process or chemical reaction proceeds spontaneously in the forward direction and similar condition is required for a reduction process also.

Hence, option A is the correct answer
