#### Given that the equilibrium constant for the reaction2SO2(g)+O2(g)  2 SO3(g)has a value of 278 at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature?SO3(g)  SO2(g)+1/2 O2(g) Option 1) 3.6 x 10-3 Option 2) 6.0 x 10-2 Option 3) 1.3 x 10-5 Option 4) 1.8 x 10-3

As we learnt in

Equilibrium constant for the reverse reaction -

Equilibrium constant for the reverse reaction is the inverse of the equilibrium constant for the reaction in the forward direction.

- wherein

is  equilibrium constant for reverse direction.
