Which of the following statements best describes Le Chatelier's principle?
- 1The total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases.
- 2A change in the variables describing a system at equilibrium causes a shift in the equilibrium position to counteract the change.✓
- 3The rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants.
- 4At a constant temperature, the volume of a given mass of gas is inversely proportional to its pressure.
Correct answer
A change in the variables describing a system at equilibrium causes a shift in the equilibrium position to counteract the change.
