Consider the following reaction at equilibrium: C( s )+H2O( g )CO( g )+H2( g ) P

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.

Part B

H2O is condensed and removed from the reaction mixture.

Part C

CO is added to the reaction mixture.

Part D

H2 is removed from the reaction mixture.

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

Explanation / Answer

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.
