Select the correct alternative for the endothermic change.

Options

A. `Delta H lt0, Delta S`(system ) `lt0`
B. `Delta H gt0, Delta S ` ( system ) `lt0`
C. `Delta H lt 0, Delta S `( surroundings ) `lt0`
D. `Delta H gt 0, Delta S `( surroundings) `lt0`

Answer

D

Explanation

For an endothermic reaction
`Delta H gt 0`
`Delta G =Delta H -T Delta S`
For a spontaneous change, `Detla G lt 0`
`Delta H-T Detla S lt 0`
`Delta S _("system")gt0`
or `Delta S_("surrounding ")lt0`
