Consider the chemical reaction: NO + Cl2 → NOCI + CI This reaction is first order in each reactant and second order overall. To measure the rate constant, k, you decide to overload the amount of Cl2, at a concentration of 4 mol/L. The NO concentration used is much lower than this value. It is a good approximation to assume that the concentration of Cl2 does not change during the time that the reaction is studied,...
