A process which is unfavourable with respect to entropy

Options

A. could occur at low temperature , but not at high temperature
B. could occur at high temperature , but not at low temperature
C. could not occur regardless of temperature
D. could not occur at any temperature

Answer

A

Explanation

Process is unfavourable with respect to entropy
`i.e., " "Delta S lt0`
For the process to be spontaneous
`Delta H -T Delta S lt0`
`implies Delta H lt0`
i.e., process is exothermic . Further, for `Delta G lt0`, T should be less i.e., low temperature will favour it.
