Chemical Equilibrium and Equation Balancing

Vocabulary practice cards reviewing Le Chatelier's principle shifts, equilibrium constant expressions, and chemical equation balancing.

Equilibrium shift from removing $C(g)$ ($\text{heat} + A(g) + B(g) \rightarrow C(g)$)

Causes the equilibrium to shift towards products.

Equilibrium shift from decreasing pressure ($\text{heat} + A(g) + B(g) \rightarrow C(g)$)

Causes the equilibrium to shift towards reactants.

Equilibrium shift from removing heat (Endothermic reaction)

Causes the equilibrium to shift towards reactants.

Equilibrium effect of adding a catalyst

Has no effect on the equilibrium position.

Equilibrium expression for $2H_2(g) + O_2(g) \rightarrow 2H_2O(g)$

$$K = \frac{[H_2O]^2}{[H_2]^2[O_2]}$$

Equilibrium expression for $3A(g) + 6B(g) \rightarrow 5C(g) + 2D(g)$

$$K = \frac{[C]^5[D]^2}{[A]^3[B]^6}$$

Balanced equation for the combustion of $C_5H_{10}$

$$2C_5H_{10} + 15O_2 \rightarrow 10CO_2 + 10H_2O$$

Balanced equation for $Ba(NO_3)_2 + H_2SO_4$

$$Ba(NO_3)_2 + H_2SO_4 \rightarrow BaSO_4 + 2HNO_3$$
