Solve this:

​Q1. ${\mathrm{A}}_2 + 2{\mathrm{B}}_2\stackrel{ }{\to }{\mathrm{A}}_2{\mathrm{B}}_4 \mathrm{and} \frac{3}{2} {\mathrm{A}}_2 + 2{\mathrm{B}}_2 \stackrel{ }{\to }{\mathrm{A}}_3 {\mathrm{B}}_4$ 
        Two substance A₂ and B₂ react in the above manner ; When A₂ is limited it gives A₂B₄, When in excess gives A₃B₄, A₂B₄ can be converted to A₃B₄ when reacted with A₂. Using this information, calculate the composition of the final mixture when mentioned amount of A₂ and B₂ are taken

(A) If 4 moles of A₂ and 4 moles of B₂ is taken in reaction container

(B) If $\frac{1}{2}$ moles of A₂ and 2 moles of B₂ is taken in reaction container

(C) If $\frac{5}{4}$ moles of A₂ and 2 moles of B₂ is taken
