Which of the following changed would not cause a shift to the products? Adding water Adding CH_4 Decreasing pressure Removing hydrogen Removing CO What is the K_a for: 1.0 times 10^-4 1.0 times 10^4 1.46 0.683 2.0 times 10^8 For a system in dynamic equilibrium which of the following statements is always true? The concentration of the products equals the concentration of the reactants. The reaction has stopped. The rate of the forward reaction equals that of the reverse. Changing the pressure will cause a shift in the equilibrium. For the reaction below which of the following changes would cause both a shift to the products and an increase in the equilibrium constant? 2NH_3 (g) doubleheadarrow 3H_2 (g) + N_2 (g) + Heat Increase pressure Decrease pressure Increase temperature Decrease temperature For the reaction: PCI_3 (g) + CI_2 (g) doubleheadarrow PCI_5 (g) How many of the following changes would cause a shift to the products? Decrease in volume Add
