$2pocl_3(g) + heat leftrightarrow 2pcl_3(g) + o_2(g)$\nfor the equilibrium system described by this equation, what happens if the temperature is decreased?\nthe equilibrium will shift right.\nthe equilibrium will shift left.\nthe equilibrium will not change.
Answer
Brief Explanations:
The given reaction has heat as a reactant, so it is an endothermic process. According to Le Chatelier's principle, decreasing the temperature (removing heat, a reactant) will shift the equilibrium to favor the reverse reaction, which produces heat. This means the equilibrium shifts left to replenish the lost heat.
Answer:
The equilibrium will shift left.
