The reaction A + 2B + C → Products has a rate law of Rate = k[A]²[B]. By what factor would the reaction rate change if [C] is tripled?

Answer 1

A + 2B + C ==> P

Rate = k[A]²[B]

If [C] is tripled, the rate of the reaction will not change because C is not included in the rate law, meaning the reaction is zero order with respect to C. Thus, reaction rate in independent of the concentration of C.
