21:11, basic, multiple choice, < 1 min, fixed. 016 (part 1 of 1) 6 points Consider the reaction C(s) + CO 2 (g) 2 CO(g) . At equilibrium at a certain temperature, the partial pressures of CO(g) and CO 2 (g) are 1.22 atm and 0.780 atm, respectively. Calcu- late the value of K for this reaction. 1. 3.13 2. 2.00 3. 1.91 correct If the initial concentration of Ni(CO)4(g)is 1.0 M, andxis the equilibrium concentra-tion of CO(g), what is the correct equilibriumrelation?

Explanation: Precipitating out CH 3 COOAg removes CH 3 COO - from the equilibrium system and shifts the equilibrium to the right, dissociat- ing more CH 3 COOH to replace CH 3 COO - . Sparks equil 006 21:15, general, multiple choice, < 1 min, fixed. 021 (part 1 of 1) 6 points The reaction A + B * ) C + D is at equilibrium. Increasing the temperature of the reaction causes more C and D to be formed. This reaction is 1. endothermic. correct
