Question

For a non-spontaneous reaction, at 30${}^0$C,$\Delta$ H>0 & $\Delta$ S > 0. The reaction becomes spontaneous,elta by

• A. Decreasing temperature
• B. Increasing temperature
• C. Maintaining temperature constant
• D. Does not maintain temperature

Answer 1

The correct option is B Increasing temperature

$\Delta G=\Delta H-T\Delta S$
for spontaneous reaction $\Delta G$ should be - ve by increasing temperature $\Delta G$ will shift towards - ve valve for $\Delta H>O$ & $\Delta S>O$
