If some forms of "stress" (adding, removing, heating, cooling, changing volume) is applied to the exothermic reaction, 2 CO(g) + O2(g) ⇋ 2 CO2(g), when it is at equilibrium, then a change will occur in the concentration(s) of

a. products only

b. neither reactants nor products

c. both reactants and products

d. reactants only

e. need to know which "stress"


We’re being asked to identify the change that will occur when a form of stress is applied to an exothermic reaction.

2 CO(g) + O2(g)  ⇋ 2 CO2(g)

According to Le Chatelier’s Principle, if a system (chemical reaction) is at equilibrium and we disturb it, then the system will readjust to maintain its equilibrium state.
