This is hard to solve algebraically but you can use your calcu-lators to get three solutions:x=0.459,x.550.992.Only one of these solutions can be the real answer. We canfgure that out by inspection.Since thefnal concentration ofBis1.00−2x,only thex=0.459solution makes sense.The other solutions give a negative concentration forB.Thus thefnal equilibrium conditions are[A]=1.00−0.459 = 0.541M(8.4)[B.00−2×0.459 = 0.082M[C]=0.459MExample 2:Consider the reactionA(g)B(g)+C(g),(8.5)whereKp=4.23×10−1. The initial partial pressure ofAis0.333atm. Determine the concentration of reactants and
