For the reaction H₂(g) + I₂(g) ⇌ 2HI(g), K_c = 50.2 at 445ºC. If [H₂] = [I₂] = [HI] = 1.75 * 10^-3 M at 445ºC, which of the following is true based on the above

Quizplus · Accepted Answer

The reaction quotient, Qc, is calculated using the initial concentrations of reactants and products. For this reaction, Qc = [HI]^2 / ([H2][I2]) = (1.75×10^-3)^2 / (1.75×10^-3 * 1.75×10^-3) = 1.75×10^-3 / 3.0625×10^-6 = 571.43. Since Qc < Kc (571.43 < 50.2), the reaction will proceed from left to right to reach equilibrium.
