The reaction occurs spontaneously if :

Options

  1. AT S < H and both H and S are + ve
  2. BT S > H and H is + ve and S is - ve
  3. CT S > H and both H and S are + ve
  4. DT S = H and both H and S are + ve

Correct answer

C. T S > H and both H and S are + ve

Step-by-step solution

G = H - T S G =-v e for spontaneous reaction When S =+v e, H =+v e and T S > H G =-v e Related Theory
