If the reaction is started with $NH_4COONH_{2(s)}$ and the equilibrium mixture has a total pressure of $3 \ atm$,then the $K_P$ for the reaction $NH_4COONH_{2(s)} \rightleftharpoons 2NH_{3(g)} + CO_{2(g)}$ is ..... $atm^3$.

For the reaction $A_{(g)} + 3B_{(g)} \rightleftharpoons 2C_{(g)}$ at $27 \, ^oC$,$2 \, moles$ of $A$,$4 \, moles$ of $B$ and $6 \, moles$ of $C$ are present in a $2 \, litre$ vessel. If $K_C$ for the reaction is $1.2$,the reaction will proceed in
