In the context of ∆G, what does it mean for a reaction to have a positive enthalpy change and a positive entropy change?

Options

  1. AThe reaction is spontaneous.
  2. BThe reaction is endothermic.
  3. CThe reaction is exothermic.
  4. DThe reaction can be spontaneous if T∆S is large enough to outweigh ∆H.

Correct answer

D. The reaction can be spontaneous if T∆S is large enough to outweigh ∆H.

Step-by-step solution

A reaction with a positive enthalpy change and a positive entropy change can be spontaneous if T∆S is large enough to outweigh ∆H.
