PLS I REALLY NEED HELP DUE FODAY For the reaction of hydrogen gas with iodine gas to make hydrogen iodide gas, H2 + 12 → 2HI, you have the following concentrations at equilibrium: [HQ] = 4.5647 x 10-3 M, [12] = 7.378 x 10-4 [HI] = 1.3544 x 10-2 M. M, and What is the equilibrium constant?
0.4997
0.54
46.33
54.47​

The equilibrium constant for the reaction is 54.47

Explanation:

The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term

The given chemical equation follows:

The expression for equilibrium constant will be:

We are given:

Putting values in above expression, we get:

Hence, the equilibrium constant for the reaction is 54.47
