I2(aq) + Write the equilibrium law for each of the following reac- tions in terms of molar concentrations: (a) H2(g) (b) 1 2 How does K for reaction (a) compare with K for reaction (b)? The heterogeneous reaction + 2HI(g) + has K = 1.6 x 10-34 at 25 °C. Sup- pose 0.100 mol of HCI and solid I2 are placed in a 1.00 L [HI] = M container. What will be the equilibrium concentrations = 7.37 X 10-13 M of HI and Cl2 in the container? 1-3</p><p>At a certain temperature, for the equilibrium Suppose a reaction vessel at this temperature contained Equilíbrio se desloca para a these three gases at the following concentrations: [PCl3] = esquerda. 0.0420 M, = 0.0240 M, [PCl5] = 0.00500 M. If the system is not at equilibrium, in which direction will the reaction proceed to get to equilibrium? At a certain temperature, the reaction CH3OH(g) has K = 0.500. If a reaction mixture at equilibrium [CH3OH] = M. contains 0.180 M CO and 0.220 M what is the concentration of CH3OH(g)? At high temperature, 2.00 mol of HBr was placed in a 4.00 L container where it decomposed to give the equi- librium 2HBr(g) =0.0955 At equilibrium the concentration of Br2 was measured to be 0.0955 M. What is K for this reaction at this tempera- ture? The reaction NO(g) reached equilibrium at a certain high temperature. Originally, the reaction vessel contained the follow- ing initial concentrations: = 0.184 M, = 0.377 M, = 0.0560 M, and [NO] = 0.294 M. The concentration of the the only colored gas in the mixture, was monitored by following the intensity of the color. At equilibrium, the concentration had become 0.118 M. What is the value of K for this reaction at this temperature? 2-3</p><p>At 25 °C, K = 0.145 for the following reaction in the solvent CCl4. 2BrCl Br2 + Cl2 = 0,011 If the initial concentration of BrCl in the solution is 0.050 M, what will the equilibrium concentrations of Br2 and Cl2 be? The equilibrium constant, for the reaction SO3(g)+NO(g) NO2(g) + SO2(g) was found to be 0.500 at a certain temperature. If = = 0.0497 mol/L 0.240 mol of SO3 and 0.240 mol of NO are placed in a [NO] = [SO3] = 0.0703 mol/L 2.00 L container and allowed to react, what will be the equilibrium concentration of each gas? The reaction H2(g) + has K = 3.2 X 10-34 at 25 °C. If a reaction vessel contains initially = M 0.0500 mol of HCI and then reacts to reach equi- librium, what will be the concentrations of H2 and Cl2? At 2000 °C, the decomposition of CO2, has K = If a 1.00 L container holding 1.00 X [CO] = 10-2 mol of CO2 is heated to 2000 °C, what will be the concentration of CO at equilibrium? At a certain temperature, K = 0.500 for the reaction NO2(g) + SO2(g) If 0.100 mol SO3 and 0.200 mol NO are placed in a 2.00 L = = 0.0281 M container and allowed to come to equilibrium, what will the and SO2 concentrations be? 3-3</p>
