We are asked to identify the effect of increasing the temperature to the amount of I2(s).
In an exothermic process, heat is released and in a chemical reaction is written as a product.
When the temperature is increased the chemical reaction will shift away from heat.
Four substances (HCl, I 2, HI, and Cl 2) are mixed in a reaction vessel and allowed to reach equilibrium in the following reaction:
2 HCl (g) + I 2 (s) ⇋ 2 HI (g) + Cl 2 (g)
Certain change is then made to this mixture. Considering the change, select the effect (increase, decrease, or no change) that the change has on the original equilibrium value of the quantity. The temperature and volume are constant, unless otherwise specified. This reaction is exothermic. Please circle the letter of the correct answer.
Change: Increase temperature Quantity: amount of I2 (g) Effect:
c. no change
