Hydrogen reacts with nitrogen monoxide to form dinitrogen monoxide (laughing gas) according to the equation: ${\mathrm{H}}_2(g)+2\mathrm{NO}(g)?{\mathrm{N}}_2\mathrm{O}(g)+{\mathrm{H}}_2\mathrm{O}(g)$ The following data are collected from the reaction. Determine the rate equation from the data. A. rate $=k[\mathrm{NO}{]}^2\left[{\mathrm{H}}_2\right]$ B. rate $=k[\mathrm{NO}{]}^2$ C. rate $=k[\mathrm{NO}]\left[{\mathrm{H}}_2\right]$ D. rate $=k[\mathrm{NO}]{\left[{\mathrm{H}}_2\right]}^2$ E. rate $=k\left[{\mathrm{H}}_2\right]$ Calculate the value for $k$. What are the correct units for $k$
