For a reaction, 2N_(2)O_(5)(g) to 4NO_(2)(g) + O_(2)(g) rate of reaction is:

The rate law for the decompoistion of gaseous N_(2)O_(5) , N_(2)O_(5)(g) rarr 2NO_(2)(g) + (1)/(2)O_(2)(g) is observed to be: r = (-d[N_(2)O_(5)])/(dt) = k[N_(2)O_(5)] A reaction machanism which has been suggested to be conisstent with this rate law is N_(2)O_(5)(g) overset(k_(eq))hArr NO_(2)(g)+NO_(3)(g) ("fast equilibrium") NO_(2) (g) + NO_(3)(g) overset(k_(1))rarr NO_(2)(g) + NO(g) + O_(2)(g) (slow) NO(g) + NO_(3)(g) overset(k_(2))rarr 2NO_(2)(g) (fast)

Gaseous N_(2)O_(5) decomposes according to the following equation: N_(2)O_(5)(g) rarr 2NO_(2)(g) + (1)/(2)O_(2)(g) The experimental rate law is -Delta [N_(2)O_(5)]//Delta t = k[N_(2)O_(5)] . At a certain temerature the rate constant is k = 5.0 xx 10^(-4) sec^(-1) . In how seconds will the concentration of N_(2)O_(5) decrease to one-tenth of its initial value ?

The rate constant k , for the reaction N_(2)O_(5)(g) rarr 2NO_(2) (g) + (1)/(2) O_(2)(g) is 2.3 xx 10^(-2) s^(-1) . Which equation given below describes the change of [N_(2)O_(5)] with time ? [N_(2)O_(5)]_(0) and [N_(2)O_(5)]_(t) correspond to concentration of N_(2)O_(5) initially and at time, t ?

For the reaction 2N_(2)O_(5)(g) to 4NO_(2) (g) + O_(2)(g) , the rate of formation of NO_(2)(g) is 2.8 xx 10^(-3) Ms^(-1) . Calculate the rate of disapperance of N_(2)O_(5)(g) .
