Question

Phosphorus pentachloride decomposes according to the chemical equation PCl5 → PCl₃ + Cl₂. What is the value of Kc for this reaction at 250°C?

Answer 1

The value of Kc for the reaction PCl5 → PCl3 + Cl2 at 250°C cannot be determined without the value of Kc.

Step-by-step explanation:

The value of Kc for the reaction PCl5 → PCl3 + Cl2 at 250°C can be determined using the equilibrium constant expression:

Kc = [PCl3][Cl2] / [PCl5]

However, the value of Kc is not provided in the given information.

Without knowing the value of Kc, we cannot calculate the equilibrium concentrations of the reactants and products.
