For an investigation a student poured a blue solution of CuSO4 into a beaker. The student placed a shiny, silver-colored strip of zinc metal in the solution and observed the changes. The student inferred that a chemical reaction occurred. What evidence supports this inference? A. The CuSO4 solution turned blue when the zinc metal was added.
B. None of these
C. A dark solid formed on the zinc metal.
D. The zinc metal remained silver-colored and shiny.

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
