Passage VII
Consider the following reaction:
At chemical equilibrium, the formation of hydrogen iodide gas (HI) occurs at the same rate as the formation of hydrogen (H2) and iodine (I2) gases.
At equilibrium, the equilibrium constant, (Keq), is the ratio of the square of the HI concentration ([HI]) to the product of the concentrations of H2 and I2. The table below shows the data collected while varying either the temperature or the initial reactant concentrations.
39. Based on the data in the table, which of the following statements best represents the relationship that exists between the Keq of a reaction and the temperature of that reaction?
Your Answer is
Correct Answer is A
Explanation
Compared with trails 1-6, when the temperature increases, K decreases
