Both $k$ and the reaction rate remain the same

(A) The rate law is given as $\text{Rate} = k [NO_2]^2$. This indicates that the reaction is zero order with respect to $CO_{(g)}$. The rate constant $k$ depends only on temperature and remains constant as long as the temperature is constant. Since the reaction is zero order with respect to $CO$,adding $0.1 \ mol$ of $CO_{(g)}$ does not change the rate of the reaction. Therefore,both $k$ and the reaction rate remain the same.
