Question

Consider the following reaction at equilibrium: C(s)+H2O(g)⇌CO(g)+H2(g) Predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances.

Part A C is added to the reaction mixture. -is added to the reaction mixture. -the reaction will shift left -the reaction will shift right -the reaction will remain unchanged Part B H2O is condensed and removed from the reaction mixture. -is condensed and removed from the reaction mixture. -the reaction will shift left -the reaction will shift right -the reaction will remain unchanged Part C CO is added to the reaction mixture. -is added to the reaction mixture. -the reaction will shift left -the reaction will shift right -the reaction will remain unchanged Part D H2 is removed from the reaction mixture. - is removed from the reaction mixture. -the reaction will shift left -the reaction will shift right -the reaction will remain unchanged

Answer 1

part:A: when C is added to the reaction mixture, the reaction remain unchanged. (The activity of pure solids and liquids is one so they does not have any effect on equilibrium.)

part:B: The reaction will shift left in order to increase the amount of h2O.

part:C: when CO is added to the reaction mixture, the reaction will shift left in order to decrease the increased amount of CO.

part:D: when H2 is removed from the reaction mixture, the reaction will shift right.
