A) \[-\frac{d[{{N}_{2}}{{O}_{5}}]}{dt}\]
B) \[-\frac{1}{4}\frac{d[{{N}_{2}}{{O}_{5}}]}{dt}\]
C) \[-\frac{1}{2}\frac{d[{{N}_{2}}{{O}_{5}}]}{dt}\]
D) \[-\frac{1}{3}\frac{d[{{N}_{2}}{{O}_{5}}]}{dt}\]
Correct Answer: C
Solution :
Rate of reaction \[=-\frac{1}{x}\frac{d[R]}{dt}=+\frac{1}{y}\frac{d[p]}{dt}\] [where, x and y are the stoichiometric coefficients of reactant R and product P respectively] \[\therefore \] \[Rate=\frac{-d[{{N}_{2}}{{O}_{5}}]}{2dt}=+\frac{1}{4}\frac{d[N{{O}_{2}}]}{dt}\] \[=+\frac{d[{{O}_{2}}]}{dt}\]
