Problem: 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) ofa. products onlyb. neither reactants nor productsc. both reactants and productsd. reactants onlye. need to know which "stress"

FREE Expert Solution

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.
