C)
If you remove hydrogen, you remove reactants, so the equilibrium will tend to increase the reactantas. The product concnetration will decrease and reactant concnetration increases
Reaction shifts to left
D)
This is exothermic, meaning the reaction relaeses heat
if you remove heat, then there is more opportunity for the reactants to form product (and heat again)
Therefore, the shift goes toward products

2 pts Question 14 Consider the reaction 2H2(g) + O2(g) → 2H2O(l) AH = -286 kJ Which of the following is true? The reaction is exothermic The reaction is endothermic The reaction is neutral with respect to energy change Heat is absorbed by the system Information is not enough to tell about the energy change
Consider the following equilibrium reaction. P4S3(g) + 8O2(g) = P4010(s) + 3SO2(9) AH = -3677 kJ If heat is removed from an equilibrium mixture of P4S3, P4010, O2, and SO2, then O Keq will decrease. the system will remain at equilibrium with no change in concentrations. the system will shift toward reactants to re-achieve equilibrium. O the system will shift toward products to re-achieve equilibrium. more information is needed to determine the effect on the equilibrium.
Consider this exothermic reaction at equilibrium: C(s) + 2H2(g) - CH2(g). Predict whether the reaction will shift left, right, or will not shift after each disturbance. Use the drop down to answer. When some H2 is removed, the reaction will When some C is added, the reaction will When the volume of the reaction mixture is decreased the reaction will When the temperature is increased, the reaction will shift right shift left not shift
For each of the following equilibria, use Le Chatelier's principle to predict the direction of reaction when the volume is increased. Drag the appropriate chemical equations to their respective bins. chemical equations: 2H2(g)+ O2 (g) ⇌ 2H2O (g), C (s) + H2O (g) ⇌ CO (g) + H2 (g), 2Fe (s) + 3H2O (g) ⇌ Fe2O3 (s) + 3H2 (g) bins: Reaction will go toward products, Reaction will go toward reagents, Reaction will remain at equilibrium
