At a certain temperature, 0.820 mol SO, is placed in a 4.50 L container. 2 50,(g) = 2 802(g) + O2(g) At equilibrium, 0.200 mol O, is present. Calculate Kc. Kc = Consider the reaction. PCI,() = PCI,(g) + CI,(g) K = 0.0420 The concentrations of the products at equilibrium are (PCIy1 = 0.290 M and [Cl] = 0.140 M. What is the concentration of the reactant, PCs, at equilibrium? [PCI) = M The elementary reaction 2H0(g) = 2H,(g) +0,(E) proceeds at a certain temperature until the partial pressures of H,O, H,, and 0, reach 0.0550 atm, 0.00700 atm, and 0.00350 atm, respectively. What is the value of the equilibrium constant at this temperature? 0.0000486 Kp = Consider the reaction. A(aq) = 2 B(aq) K = 8.38 x 10-6 at 500 K If a 4.90 M sample of A is heated to 500 K, what is the concentration of B at equilibrium? M [B] =
