Which of the following statements is true about the equilibrium constant? (2019)
Step 1: Understand what the equilibrium constant (Kc) is. It is a number that tells us the ratio of the concentrations of products to reactants at equilibrium in a chemical reaction.
Step 2: Recognize that Kc is not a fixed number; it can change. This change happens when the temperature of the reaction changes.
Step 3: Remember that for a specific reaction at a specific temperature, Kc will remain constant. This means if you measure Kc at 25 degrees Celsius, it will be the same every time you measure it at that temperature.
Step 4: Conclude that the statement about Kc being temperature-dependent is true, as it changes with temperature but is constant for a given reaction at a specific temperature.
