Please help with question 1
Consider the following equilibrium system: 2 NOCI(g) 2 2 NO(g) + Cl2(g) Kc = 57.0 Initially, only NOCI gas is placed in a flask. After equilibrium has been reached it is found that the concentration of the nitrogen monoxide gas in the flask is 1.14 mol/L. What is the initial molar concentration of the NOCI gas? Answer to three decimal places.
Question 20 Which statement best describes general equilibrium? Equilibrium is reached when the reaction stops. There is only one set of equilibrium concentrations that equals the Kc value. At equilibrium, the rate of the forward reaction is the same as the rate of the reverse reaction. At equilibrium, the total concentration of products equals the total concentration of reactants.
