In this section, you will compare pure water to a 1.0 L buffer solution of 0.10 M HNO2 and 0.10 M NO2-. The Ka of HNO2 is 6.8 x 10-4. Identify the weak acid and conjugate base in the buffer.

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
