Observe the following equilibrium in a 1 L flask. $$ A(g) \rightleftharpoons B(g) $$ At $\mathrm{T}(\mathrm{K})$, the equilibrium concentrations of A and B are 0.5 M and 0.375 M respectively. 0.1 moles of A is added into the flask and heated to $\mathrm{T}(\mathrm{K})$ to establish the equilibrium again. The new equilibrium concentrations (in $M$ ) of $A$ and $B$ are respectively
