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.
37. Based on the information in the table, as the initial concentrations of H2 and I2 are both doubled, the final concentration of HI:
Your Answer is
Correct Answer is D
Explanation
Comparing trail 3 and trail 7, the temperature and K are the same, but the initial concentrations in trial 7 are doubled, and the final concentration is about doubled
