Question
A student performs a kinetic experiment on the first-order kinetics of the reaction: N_2O4 rightarrow 2NO+O_2. She calculates the first-order decomposition of the reactant using the relationship: [N_2O_4]_t=[N_2O_4]_0e^-kt using the first-order rate constant k = 0.750 s^-1 and the following data: initial mass of N_2O_4: 25.7 plusminus 0.3 g, initial volume of N_2O_4: 0.22 plusminus 0.01 L, and time t = 3.8 plusminus 0.2 s. Use error analysis to calculate her reported concentration of N_2O_4 including the range of uncertainty.Explanation / Answer
given
k = 0.750
t=3.8
N2O4=N2O4e^-k
it is first order kinetics so A first-order reaction is a reaction that proceeds at a rate that depends linearly on only one reactant concentration.
Rate=d[A]dt=k[A]1=k[A
