Question

Statement 1: A non-spontaneous endothermic reaction at room temperature may be spontaneous at high temperature.
Statement 2: At high temperature $T\Delta S $ becomes more than . $T\Delta H$

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1
• B. If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1
• C. If Statement 1 is true but Statement 2 is false
• D. If Statement 1 is false but Statement 2 is true

Answer 1

Answer: (A)

For a spontaneous reaction $\Delta G=\Delta H-T\Delta S, if \Delta H=+ve \Delta G$ will be negative when $T\Delta S >\Delta H$
