QUESTION 12 At a certain temperature, the equilibrium constant $K_c = 6.75 \times 10^{-3}$ for the equilibrium reaction below. A technician started a reaction using initial concentrations of $[CH_4] = 2.0 M$ and $[H_2O] = 2.0 M$. $CH_4(g) + H_2O(g) \rightleftharpoons CO(g) + 3H_2(g)$ From the equilibrium equation, define the equilibrium constant $K_c$ in terms of $x$ (if $x$ denotes a change in the concentrations of $[CO]$ and $[H_2]$). Assume $2-x \approx 2$ because $K_c < 0.01)$. use the $X,Y$ function in your calculator to solve for $x^4 = ...)$ O A. $[CO] = 0.178M$ and $[H_2] = 0.534M$ O B. $[CO] = 27.0M$ and $[H_2] = 81.0M$ O C. $[CO] = 0.5M$ and $[H_2] = 1.5M$ O D. $[CO] = 3.0M$ and $[H_2] = 1.0M$
