If an eddothermic reaction occurs spontaneously at constant temperature and pressure, then which of the following is true?A. `Delta S lt 0`B. `Delta S gt 0`C. `Delta H lt 0`D. `Delta G gt 0` |
|
Answer» Correct Answer - B According to thermodynamics (at constant `T` and `P`) `Delta G = Delta H - T Delta S` For reaction to be spontaneous, `Delta G` should be negative `(lt 0)`. Since the reaction is endothermic, `Delta H` is positive `(gt 0)`. Thus, `T Delta S` should be positive and greater than `Delta S` must be positive `(gt o)`, |
