Q$\mathrm{.}26$ Consider the following reaction:A$($s$)+$ B$($g$)->$ C$($s$)+$ D$($g$)$Determine the equilibrium fraction of B which reacts at $500\backslash$deg C if equal number of molesof A andB are introduced into the reactor initially. The equilibriunm constant for thereaction at $500\backslash$deg C is $2\mathrm{.}0.($Rounded off to two decimal places$)$
