For the reaction $\mathrm{A}\left(\mathrm{g}\right)+\mathrm{B}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{C}\left(\mathrm{g}\right)$ at equilibrium the partial pressure of the species are ${\mathrm{P}}_{\mathrm{A}}=0.15\mathrm{atm},{\mathrm{P}}_{\mathrm{C}}={\mathrm{P}}_{\mathrm{B}}=0.30\mathrm{atm}$. If the capacity of reaction vessel is reduced, the equilibrium is re-established. In the new situation partial pressure A and B become twice. What is the partial
