Question

Consider the reaction 2H2 (g) + O2 (g) 2H2O(g) How will the equilibrium shift when hyDragen gas is removed? The reaction will shift toward both the reactants and products. The reaction will not shift toward either the products or reactants. The system will shift toward the reactants. The system will shift toward the products. Consider the exothermic reaction Fe2O3(s) + 2Al(s) Al2O3(s) + 2Fe(s) In what direction will the equilibrium shift when heat is removed? The reaction will shift toward both the reactants and products. The equilibrium will shift toward the reactants. The equilibrium will shift toward the products. The reaction will not shift toward either the products or reactants.

Explanation / Answer

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
