Q
Q: For the equilibrium reaction CO(g) + 2H2(g) ⇌ CH3OH(g), if the temperature is decreased, what will be the effect?
Solution: Decreasing the temperature for an exothermic reaction will shift the equilibrium to the right, favoring the formation of products.
Steps: 5
Step 1: Identify the reaction type. The reaction CO(g) + 2H2(g) ⇌ CH3OH(g) is an exothermic reaction, meaning it releases heat.
Step 2: Understand Le Chatelier's Principle. This principle states that if a system at equilibrium is disturbed, it will shift in a direction that counteracts the disturbance.
Step 3: Recognize the disturbance. In this case, the disturbance is a decrease in temperature.
Step 4: Determine the effect of decreasing temperature. Since the reaction is exothermic, decreasing the temperature will favor the side that produces heat, which is the product side (CH3OH).
Step 5: Conclude the effect. Therefore, decreasing the temperature will shift the equilibrium to the right, favoring the formation of CH3OH.
