Please solve these two problem with solution. I really need it.

K = 1.5 x 106 5. Consider the hypothetical equation: Ag) = 2B) A. Write the equilibrium expression for the reaction? (1 pt) K= B. If the reaction above is written in reverse: 2Bg) = A(9), What will be the corresponding expression? (1 pt) K= C. What will be the value for the equilibrium constant for the reverse reaction? (1 pt) K= 6. Sulfuric acid (H2SO4) dissociates according to the following reactions. H2SO4(aq) = H+ (aq) + HSO4 (aq) K4 = 1.0 x 103 HSO4 (aq) = H+ (aq) + SO42 ta K2 = 1.2 x 102 (aq) A. Acids are stronger when they give off more H+ , given the values of K, and K2, which is a stronger acid, H2SO4 or HSO4? Explain your answer. (3 pts) B. What is the value of the equilibrium constant for the reaction: (2 pts) H2SO4(aq) = 2H+ (aq) + SO42- (aq)
