Question

At 473 K. equilibrium constant, K, for the decomposition of phosphorus pentachloride PCI5, 8.3 * 10^-3
PCI5 (g) <= =>PC13,(g)+Cl2(g) Hº=124 kJ mol^-1
1Write an expression of K for the reaction.
2What is the value of K for the reverse reaction at the same temperature?
3What would be the effect on K if the temperature is increased?​

Answer 1

Answer:

The number of atoms in S₈ : 6.02 × 10²³ × 0.25 = 1.505 × 10²³ atoms.
