If the concentration of NO is halved in a reaction with the rate law rate = k(NO)²(H₂), the rate of the reaction would decrease. Specifically, since the rate is proportional to the square of the concentration of NO, reducing its concentration by half would result in the rate being reduced to one-fourth of its original value, assuming the concentration of H₂ remains constant. Therefore, the new rate would be k(0.5NO)²(H₂) = k(0.25NO²)(H₂) = (1/4) × original rate.
In the given rate law, the rate of the reaction is dependent on the concentration of NO and possibly other reactants. If the concentration of NO is halved, the rate of the reaction would decrease proportionally, assuming that NO is a reactant in the rate law. Specifically, if the rate law is of the form rate = k[NO]^n[other species], the rate would be affected by the new concentration of NO, resulting in a reduced reaction rate. The exact impact on the rate would depend on the order of the reaction with respect to NO.
The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.
