The gas phase irreversible reaction $2A+$Blongrightarrow$3C$ takes place in an isothermal batch reactor with an initial volume of $200L.$ The reactor is loaded with equimolar quantities of A and B and with $200$ moles in total initially. The reaction is first order withrespect to A and first order with respect to $B.$

How much is the concentration of product $C$ when the degree of conversion is $0\mathrm{.}8?$ How much is the concentration of reactant $B$ when the degree of conversion is $0\mathrm{.}8?$ How much is the concentration of reactant A when the degree of conversion is $0\mathrm{.}8?$
