Q$3.$ The elementary liquid$-$phase reversible reaction,

occurs in an isothermal batch reactor. The forward and reverse reaction rate constants at $70C$ are $0\mathrm{.}035$ and $0\mathrm{.}023L.mo{l}^{-1}*mi{n}^{-1}$ respectively. The molar feed composition is $50\%$A and $50\%B.$

$>0b^{}=343\mathrm{.}15h$

$($a$)$ Determine the equilibrium conversion of $A$ at the reaction temperature of $70C.$ Fina $x_A$ as $>0.$

reaction rate $=0\mathrm{.}035Lmo{l}^{-1}*mi{n}^{-1}$

$($b$)$ Determine the time required to achieve $80\%$ of the equilibrium conversion. Write down the process steps involved in a heterogeneous catalytic reaction.
