Use the reaction and information below for questions 1 - 3 CH_4 (g) + H_2 O(1) CO(g) + 3H_2(g) K_ = 1.0 times 10^-4.T = 25 degree C, R = 0.0821 What is the value for K_ ? 1.0 times 10^4 1.0 times 10^-4 1.46 0.683 49.65 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) 3H_2(g) + N_2 (g) + Heat Increase pressure Decrease pressure Increase temperature. Decrease temperature 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_ for: CO(g) + 3H_2(g) CH_4(g) + H_2 O(1) 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: PCI_3(g) + CI_2(g) PCI_5(g) How many of the following changes would cause a shift to the products? Decrease in volume Add a catalyst Add cl_2 gas Decease |PCl_5] 0 1 2 3 4 For the reaction below is the dissociation of a weak acid in water.
