[Note that the HSO3 in equation 3 is not the same as the (neutral) HSO3 in eqs. 6 and 7]. See Suchecki,

2005.

With this information:

a) Combine equations 3 through 7 to obtain equation 1 (i.e., use Hess' Law).

b) Write the mathematical expression for each equilibrium constant corresponding to reactions 3 to 7 (i.e., Kj, K4, K5, K(„ and X7).

c) Derive the rate equation (equation 2) by assuming that the initial concentration of HSO3 is so large
