Question 1
For the following reaction find
Kp at 25°C and indicate whether
Kp should increase or decrease as the temperature rises.
NH4HS(s) ⇌ H2S(g) + NH3(g) | ΔH° = 83.47 kJ and ΔG° = 17.5 kJ at 25°C. |
◦
Kp = 8.6 × 10
-4 and
Kp should decrease as the temperature rises.
◦
Kp = 1.2 × 10
3 and
Kp should decrease as the temperature rises.
◦
Kp = 1.2 × 10
3 and
Kp should increase as the temperature rises.
◦
Kp = 8.6 × 10
-4 and
Kp should increase as the temperature rises.
Question 2
If Δ
G is small and positive,
◦ the forward reaction is spontaneous and the system is far from equilibrium.
◦ the reverse reaction is spontaneous and the system is near equilibrium.
◦ the forward reaction is spontaneous and the system is near equilibrium.
◦ the reverse reaction is spontaneous and the system is far from equilibrium.
