Given the reaction \( 2NO + O_2 \rightarrow 2NO_2 \), if the initial concentrations of NO and \(O_2 \) are 0.5 M and 0.25 M respectively, and the rate constant ( k ) is 0.1 \( M^{-1} s^{-1} \), what will be the rate of the reaction?
1
0.0125 \(M s^{-1} \)
2
0.00625 \(M s^{-1} \)
3
0.05 \(M s^{-1} \)
4
0.1 \(M s^{-1} \)
