Dissociation of a gas $$A_{2}$$ takes place according to the following chemical reaction.
At equilibrium, the total pressure is 1 bar at 300K.

$$A_{2}(g)\rightleftharpoons 2A(g)$$

The standard Gibbs energy of formation of the involved substances has been
provided below:

The degree of dissociation of $$A_{2} (g)$$ is given by $$(x\times10^{-2})^{1/2} $$ where $$x$$ =
_____ . (Nearest integer).
[Given: $$R=8 J \text{ }mol^{-1}K^{-1},\log{2}=0.3010, \log {3}=0.48]$$
Assume degree of dissociation is not negligible.
