Question

1.
The equilibrium concentration in a gas mixture at a particular temperature are 0.13 M
H2. 0.70 M 12 and 2.1 M HI. What equilibrium concentration are obtained at the same
temperature when 0.20 mole of HI is injected into an empty container?
(A) [H2] = [12] = 0.045 M
(B) [HI] = 0.31 M
(C) [H2] = 0.31 M
(D) [HI] = 0.045 M​

Answer 1

Answer:

your answer is [H2] = 0•31 M
