Group Work 3 CHM 152 Laona Burk Name: ___________________________________ due 3-24-09 K p = K c (RT) Δ n R = 0.08206Latm/molK 1. Reactants are mixed together and a reaction occurs. Once equilibrium is reached, the equilibrium constant is found to be 20. What will happen if the product chemicals of the same reaction are mixed together? a. Nothing, products are formed so there will be no reaction. b. The products will react and reach equilibrium with an equilibrium constant value of 1/20. c. The products will react and reach equilibrium with an equilibrium constant value of 20. d. The reaction will stop once equilibrium is reached. e. Equilibrium will be reached when the concentration of the reactants equal the products. 2. If the equilibrium constant K has a value of 3.52 x 10 -5 we say that ___________________ is favored. 3. Calculate the numerical values of K c and K p at 27.5 o C for the reaction of carbon monoxide gas with hydrogen gas forming methanol (CH 3 OH) gas if the partial pressures of carbon monoxide is 0.835 atm,
