First order reaction : The rate of reaction which depends only on one concentration term
For the reaction `Rto p, Rate =-(d[R])/(dt)=k[R] " "{:([R]"Concentration of reactant"),(K- "First order rate constant"):}`
1) Decomposition of `N_(2) O_(5)" "N_(2)O_(5)(g) to to 2NO_(2) (g) +1//2 O_(2)(g)`
2) Decomposition of `N_(2)O" "N_(2)O(g) to 2_(2(g))to N_(2(g)) +1//2 O_(2(g))`
