For the reaction, \[2{{N}_{2}}{{O}_{5}}\to 4N{{O}_{2}}+{{O}_{2}}\] the rate equation can be expressed in two ways\[-\frac{d[{{N}_{2}}{{O}_{5}}]}{dt}=k[{{N}_{2}}{{O}_{5}}]\] and \[+\frac{d[N{{O}_{2}}]}{dt}=k'[{{N}_{2}}{{O}_{5}}]\] k and k' are related as:

• A. \[k=k'\]                         
• B. \[2k=k'\]
• C. \[k=2k'\]                       
• D. \[k=4k'\]
