Questions & Step-by-Step Solutions
In the reaction H2(g) + I2(g) ⇌ 2HI(g), what happens if the concentration of HI is increased?
Step 1: Understand the reaction: H2(g) + I2(g) ⇌ 2HI(g) means that hydrogen (H2) and iodine (I2) can combine to form hydrogen iodide (HI).
Step 2: Recognize that the reaction can go in both directions: it can produce HI or break down HI back into H2 and I2.
Step 3: Know that equilibrium means the reaction is balanced, and the amounts of H2, I2, and HI remain constant.
Step 4: Le Chatelier's Principle states that if you change the conditions of a reaction at equilibrium, the system will adjust to counteract that change.
Step 5: If you increase the concentration of HI, the system will try to reduce the amount of HI to restore balance.
Step 6: To reduce HI, the reaction will shift to the left, meaning it will produce more H2 and I2 from HI.
