A reaction occurs spontaneously if:A. `T Delta S lt Delta H` and both `Delta H` and `Delta S` are `+ ve`B. `T Delta S gt Delta H` and both `Delta H` and `Delta S` are `+ ve`C. `T Delta S = Delta H` and both `Delta H` and `Delta S` is `+ ve`D. `T Delta S lt Delta H` and `Delta H` is `+ ve` and `Delta S` is `-ve` |

Answer» Correct Answer - B According to thermodynamics, `Delta G = Delta H - T Delta S` If both `Delta H` and `Delta S` are positive, then `Delta G` will be negative only when the `T Delta S` term is greater in magnitude than `Delta H`. |
