7.6 Properties of K and 7.7 Calc Equilibrium Concentrations

Calculate K_p for the reaction:

• proceeds to products

• proceeds to reactants

• at equilibrium

• [CO₂] = [H₂] because they are in a 1:1 mole ratio in the balanced equation.

• The total concentration of reactants is equal to the total concentration of the products.

• The total concentration of reactants is greater than the total concentration of the products.

• The total concentration of products is greater than the total concentration of the products.

• None of these are true
