Step 1

A reversible chemical reaction can move in either forward or backward direction. The stage of a reversible reaction at which the rate of forward and backward reaction become equal to each other is called an equilibrium stage.

The equilibrium constant for a reaction is the ratio of equilibrium concentration of product and reactant. If the reaction is given in gaseous state, then the equilibrium pressure must be considered.

Step 2

Part (a)

The Kp value is given for the formation of SO3 at 1000 K as 1.85. For the reaction of conversion of SO3 to SO2 must be backward reaction of the formation of SO3.

Hence the Kp must be inverse value:

Step 3

Part (b):

The given reaction is just double to the reaction of formation o...
