This system has an equilibrium constant of 50.5 at 448°c: h2(g) + i2(g) ↔ 2hi(g). what is the reaction quotient, q, for this system when [h2] = 0.200 m, [i2] = 0.100 m, and [hi] = 3.00 m?

For a general reaction:

Expression for reaction quotient is written as follows:

Here, [A], [B], [C] and [D] is concentration of A, B, C and D respectively and a, b , c and d is their respective stoichiometry.

The given reaction is as follows:

Thus, expression for reaction quotient will be:

Putting the values,

Therefore, the value of reaction quotient is 450.

the answer is either b or c
