I need help with question all questions. Thank you
1. Write an expression for Keq for each of the following reactions a. b. c. COC12(g) + CO(g) â CO(g) + Cl2(g) CS2(g) + 4H2(g) â 2H,S(g) + CH4(g) 2SO2(g) + 02(g) â2503(g) 2. Consider the following equilibrium constants. How would the concentration of products compare to the concentration of reactants (mostly products, mostly reactants, or about the same) in each case? a. Keq=0.00036 b. Keq_ 2.1 c. Keq = 3.3 x 108 d. Keq 2.7 x 106 3. Consider the reaction once it has reached equilibrium: N2(g) + 3H2(g) 2NH3(g) What will happen in each of the following cases (forward reaction will occur, reverse reaction will occur, or no change)? a. More nitrogen gas is added b. Some hydrogen gas is removed c. Some ammonia (NH3) is added d. The volume is decreased 4. Pyridine (CSHsN) is a base even though it does not contain the hydroxide ion. Write a chemical equation that describes how pyridine can be an Arrhenius base when it is dissolved in water 5. The pH of your blood is 7.4. W hat is the molar concentration of hydroxide ions [OH] ir your blood?
