Question

For a reaction: A + 2 B rightarrow 3 C, the reaction spontaneity can be determined by comparing the reaction quotient Q and equilibrium constant K. If the forward direction is spontaneous, If the forward direction is non-spontaneous, At equilibrium. The decomposition reaction of H_2CO is: H_2CO (g) CO (g) + H_2 (g). How does the pressure influence the equilibrium? Increasing the total gas pressure, P_total, favors the decomposition of H_2CO Decreasing the total gas pressure, P_total, favors the decomposition of H_2CO The total gas pressure, P_total, has no effect on the decomposition of H_2CO For reaction 3 H_2 (g) + N_2 (g) 2 NH_3 (g), how does the pressure influence the equilibrium? Increasing the total gas pressure, P_total, favors the formation of NH_3. Decreasing the total gas pressure, P_total, favors the formation of NH_3 The total gas pressure, P_total, has no effect on the formation of NH_3 For Reaction: HCl (g) + NH_3 (g) NH_4CI (s), the forward direction has Delta H degree = -176 kJ/moI. Which one of the following is true? Increasing temperature will favor the formation of NH_4CI (s) Decreasing temperature will favor the formation of NH_4Cl (s) Temperature has no effect on the formation of NH_4CI (s)
