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