two principles:the steps in a mechanism are elementary reactions, so the exponents in the rate laws are the coefficients in the steps. no reaction can go faster than its slowest step.
(d) r₂ ⟶ 2r (slow); rate = k[r₂]
(a) is wrong. rate = k[q][r₂]. reaction is 1st order in q.
(b) is wrong. rate = k[q]². reaction is 2nd order in q.
(c) is wrong. rate = k[q][z]. reaction is 1st order in q and 1st order in z.
yeah, a lot faster than sound.
depending on the type of food it is either called oxidation or lipid peroxidation. hope this
