# Problem: A sample of S8(g) is placed in an otherwise empty rigid container at 1325 K at an initial pressure of 1.00 atm, where it decomposes to S2(g) by the reactionS8(g) ⇌ 4S2(g)At equilibrium, the partial pressure of S8 is 0.25 atm. Calculate Kp for this reaction at 1325 K.

###### FREE Expert Solution

(1) Setup an ICE chart (2) At equilibrium, S8 temperature is 0.25 which means:

1 - x = 0.25

x = 0.75

A sample of S8(g) is placed in an otherwise empty rigid container at 1325 K at an initial pressure of 1.00 atm, where it decomposes to S2(g) by the reaction

S8(g) ⇌ 4S2(g)

At equilibrium, the partial pressure of S8 is 0.25 atm. Calculate Kp for this reaction at 1325 K.
