Given the reaction at a certain temperature: 2 HI(g)⇌ H₂(g)+ I₂(g).At equilibrium,the partial pressure of HI is 1.8 × 10^-3 atm,and the partial pressures for H₂ and I₂ are 0.10 atm each.Find K_p at that temperature.

Question

Quizplus · Accepted Answer

First, write the expression for the equilibrium constant (Kp) using the partial pressures:

Kp = (P(HS2))/²(P(HI))

Substitute the given values into the expression:

Kp = (0.10²)/(1.8×10⁻³)² = 3.1×10⁻¹³

Therefore, the correct choice is C.
