7. The reaction of NO with Clz proceeds in a fixed container as follows.

Which of the following statements is (are) correct?(AB) The forward rate cquals the reverse rate when the reaction is in equilibrium.(AC) The reaction rate is determined by the collision between NO(g) and Cl2(g) molecules.(AD) Increasing the concentration of Cl2(g) will increase the reaction rate.(AE) Removing NOCI(g) from the reaction mixture will increase the reaction rate.(BC) The reaction is a second-order reaction.(BD) The unit of k in the rate law of the reaction is L/mol-s. if the concentration of the reactant is expressed in mol/L and therate in mol/L-s.
