IntermediateMCQMathematical18.9k
The initial rates of the reaction represented below were measured at \(298\text{ K}\) for several different initial concentrations of \(\text{NO}(g)\) and \(\text{Br}_2(g)\).

\[ 2\text{NO}(g) + \text{Br}_2(g) \rightarrow 2\text{NOBr}(g) \]

TrialInitial \([\text{NO}]\) (\(\text{M}\))Initial \([\text{Br}_2]\) (\(\text{M}\))Initial rate of formation of \(\text{NOBr}\) (\(\text{M}\cdot\text{s}^{-1}\))
\(1\)\(0.10\)\(0.20\)\(2.4 \times 10^{-3}\)
\(2\)\(0.20\)\(0.20\)\(9.6 \times 10^{-3}\)
\(3\)\(0.10\)\(0.40\)\(4.8 \times 10^{-3}\)

Based on the experimental data, what is the value of the rate constant, \(k\), for the reaction at \(298\text{ K}\)?
