The equilibrium constant Kc at 298 K for the reaction $\mathrm{A}+\mathrm{B} \rightleftharpoons \mathrm{C}+\mathrm{D}$ is 100 . Starting with an equimolar solution with concentrations of $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and D all equal to 1 M , the equilibrium concentration of D is $\_\_\_\_$ $\times 10^{-2} \mathrm{M}$.
