We’re being asked to determine the rate constant (k) of N2O5.
Recall that half-life is the time needed for the amount of a reactant to decrease by 50% or one-half.
The half-life of a first-order reaction is given by:
t1/2 = half-life
k = decay constant
The half-life of N2O5 (g) at a 25 °C is 4.03 x 104 s.
a) Find the rate constant (k) for the first-order decomposition of N2O5 (g) at 25 °C.
