Q: For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), what happens to the equilibrium constant if the temperature is increased?
Solution: For exothermic reactions, increasing the temperature shifts the equilibrium to the left, thus decreasing the equilibrium constant.
Steps: 4
Step 1: Identify the type of reaction. The given reaction is N2(g) + 3H2(g) ⇌ 2NH3(g). This reaction is exothermic, meaning it releases heat.
Step 2: Understand what happens when temperature increases. For exothermic reactions, increasing the temperature adds heat to the system.
Step 3: Apply Le Chatelier's Principle. According to this principle, if you add heat to an exothermic reaction, the equilibrium will shift to the left to absorb the extra heat.
Step 4: Determine the effect on the equilibrium constant. When the equilibrium shifts to the left, the concentration of reactants increases and the concentration of products decreases, which results in a decrease in the equilibrium constant.
