A student investigates the kinetics of the gas-phase reaction represented by the equation 2 \(\text{NO(g)}\) + \(\text{Cl}_2\text{(g)}\) \(\rightarrow\) 2 \(\text{NOCl(g)}\). The initial-rate data collected from three experimental trials at 298 K are shown in the table below.

Trial	Initial \([\text{NO}]\) (M)	Initial \([\text{Cl}_2]\) (M)	Initial rate of formation of \(\text{NOCl}\) (M/s)
1	0.10	0.10	\(1.2 \times 10^{-3}\)
2	0.20	0.10	\(4.8 \times 10^{-3}\)
3	0.10	0.30	\(3.6 \times 10^{-3}\)

Based on these data, what is the value and units of the specific rate constant, \(k\), for the reaction?
