The differential rate law for the reaction A + 3B + 4C → Products is given by the following equation:
dxdt = kA B.
What will be the effect on the rate of reaction if the concentration of C is doubled?

The rate of reaction is express only by [A][B] i.e.dxdt = kA B.Thus no effect is occur when the concentration of c is doubled.
