Use the fact that A(g)⇌B(g)+C(ℓ) KC=15.2 and D(s)⇌F(g) KC=0.45 to calculate the value of KC for the reaction 3A(g) + F(g) ⇌ 3B(g) + 3C(l) + D(s)
5.(3 pt) Kc for the following reaction is 0.212 at 1000C.N2O4(g)→2 NO^2(g)A student running this reaction in the lab measures the concentrations as[N2O4] = 0.33 M and [NO2] = 0.66M. They conclude that the reaction must have reached equilibrium because there is a 2:1 ratio of products to reactants, just like in the balanced chemical equation. Decide if the student is right or wrong and explain your reasoning. If the student is right, prove they are right by verifying their...
