Question
The rate information below was obtained for the following reaction at a constant temperature.
\[2{\text{N}}{{\text{O}}_2}({\text{g)}} + {{\text{F}}_2}({\text{g)}} \to {\text{2N}}{{\text{O}}_2}{\text{F(g)}}\]
What are the orders of the reaction with respect to \({\text{N}}{{\text{O}}_{\text{2}}}\) and \({{\text{F}}_{\text{2}}}\)?
A. \({\text{N}}{{\text{O}}_{\text{2}}}\) is first order and \({{\text{F}}_{\text{2}}}\) is second order
B. \({\text{N}}{{\text{O}}_{\text{2}}}\) is second order and \({{\text{F}}_{\text{2}}}\) is first order
C. \({\text{N}}{{\text{O}}_{\text{2}}}\) is first order and \({{\text{F}}_{\text{2}}}\) is first order
D. \({\text{N}}{{\text{O}}_{\text{2}}}\) is second order and \({{\text{F}}_{\text{2}}}\) is second order
