Question

Consider the following equilibrium which is exothermic in the forward reaction: [Ni(Cl)4]2- (aq) + 4 NH3 (aq) ? [Ni(NH3)4 ]2+ (aq) + 4 Cl- (aq) Select all of the following that will shift the equilibrium to the right (more products). Decreasing the temperature. Adding KCl (aq). Adding a catalyst. Increasing the temperature. Adding ammonia (NH3). None of the these changes will shift the equilibrium to form more product.

Step 1

Decreasing the temperature: Since the forward reaction is exothermic, decreasing the temperature will shift the equilibrium to the right (more products) to compensate for the loss of heat. So, this option is correct. Show more…

Consider the following equilibrium, which is exothermic in the forward reaction: [Ni(Cl)4]2- (aq) + 4 NH3 (aq) ⇌ [Ni(NH3)4 ]2+ (aq) + 4 Cl- (aq). Select all of the following that will shift the equilibrium to the right (more products). Decreasing the temperature. Adding KCl (aq). Adding a catalyst. Increasing the temperature. Adding ammonia (NH3). None of these changes will shift the equilibrium to form more product.
