Question

question 5 (1 point)
which of these affects the equilibrium constant, $k_{eq}$.

a) concentration

b) pressure

c) volume

d) temperature

e) all of the above

Explanation:

The equilibrium constant \( K_{\text{eq}} \) is a characteristic of a chemical reaction at a given temperature. Concentration, pressure, and volume changes can shift the equilibrium position (Le Chatelier's principle) but do not change \( K_{\text{eq}} \). Temperature affects \( K_{\text{eq}} \) because the equilibrium constant is related to the Gibbs free energy change (\( \Delta G = -RT\ln K_{\text{eq}} \)), and temperature (\( T \)) is a variable in this relationship. A change in temperature changes the value of \( K_{\text{eq}} \) as it affects the energy of the reaction (exothermic or endothermic reactions have \( K_{\text{eq}} \) dependent on temperature).

Answer:

d) temperature
