If the reaction below is initially at equilibrium, and then each of the following changes are made, predict which direction the reaction rate will be fastest until equilibrium is once again established: forward, reverse, or no change. 2 CO(g) + O2(g) → 2CO2(g) a. The concentration of O2 is increased. forward b. The concentration of CO2 is decreased? forward c. The concentration of oxygen gas is decreased. reverse 2. If the reaction below is initially at equilibrium, and then each of the following changes are made, predict which direction the reaction rate will be fastest until equilibrium is once again established: forward, reverse, or no change. a. adding H₂O(g) forward b. removing H₂ forward C(s) + H₂O(g) CO(g) + H2(g)

Expert Solution
Step 1

Le Chatelier's principle:

According to the Le Chatelier's principle when a change in concentration temperature and pressure applied on the system at equilibrium, the position of the equilibrium shift in the direction that tends to reduce the effect of that change.
