Which of the following statements best describes Le Chatelier's principle?
- AThe law states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases.
- BThe principle states that the rate of a chemical reaction is directly proportional to the concentration of the reactants.
- CThe principle states that changes in conditions describing a system at equilibrium cause shifts in the equilibrium position to counteract the change.
- DThe law states that the volume of a gas at constant temperature is inversely proportional to its pressure.
Solution & Step-by-step Explanation
Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions (such as temperature, pressure, or concentration of reactants), the position of equilibrium shifts in a direction that tends to counteract or undo the change.
