Consider the hypothetical reaction A(g)+2B(g)?2C(g), for which Kc=0.25 at some temperature

Consider the hypothetical reaction A(g)+2B(g)?2C(g), for which Kc=0.25 at some temperature. A 1.00-L reaction vessel is loaded with 1.00 mol of compound C, which is allowed to reach equilibrium. Let the variable x represent the number of mol/L of compound A present at equilibrium.In terms of x, what are the equilibrium concentration of compound B? Express your answer in terms of x. In terms of x, what are the equilibrium concentration of compound C? Express your answer in terms of x. y putting the equilibrium concentrations (in terms of x) into the equilibrium-constant expression, derive an equation that can be solved for x. Express your answer in terms of x.
