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.

36. Which of the following pairs of trials in the table shows that reversing the initial concentrations of H2 and I2 at the same temperature gives the same final concentration of HI ?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

Look at trail 9 and trail 10 in table 1, Initial [H2] and Initial [I2] in the two groups are interchanged, but the Final The values ​​are all the same; so are trail 11 and trail 12
