K 128.6 How much PCs would be present if 0.742M of PCh and 0.541M of Cl were found in a sealed reaction vessel at equilibrium? (516) 2. For the reaction N2 + 3H2<-> 2NH3, what should be the equilibrium concentration of NH3 if the value of the reaction is 103.4 and the equilibrium concentrations of N2 and H2 are (0.035) and (23) respectively? (6.6) 3. Nitrogen monoxide reacts with hydrogen gas to form water and nitrogen gas 2NO+2H,2H,O+N; Initially, 1.08M of NO and 2.41M of Hy were added to a sealed container, and the system was allowed to reach equilibrium. If 0.74M of NO was present when the reaction reached equilibrium, what is the concentration of H3, H O and N; at equilibrium? [H2)-2.07. [H201=0.34, IN2]=0.17, Find K to 5 decimal place. K 0.02463 4. Chloromethane reacts with ammonia to form methylamine and hydrochloric acid CH,CINH, CH,NH2 + HCI K=? Initially, 2.08M of CH3Cl and 2.16 M of NH, were added to a sealed container, and the system was allowed to reach equilibrium. If 1.56M of NH, was present when the reaction reached equilibrium, what is the equilibrium constant for this reaction? Also find equilibrium concentrations if CH3CI, CH3NH2 and HCI. [CH3CIJ=1.48 M, CH3NH2)-0.6HCI). K0.156
