1. The decomposition of acetaldehyde is a second order reaction with a rate constant of 4.71 × 10^−8 L/mol/s.

What is the instantaneous rate of decomposition of acetaldehyde in a solution with a concentration of 5.55 × 10^−4 M?

2. The rate constant for the first-order decomposition at 45 °C of dinitrogen pentoxide, N2O5, dissolved in chloroform, CHCl3, is 6.2 × 10^−4 min^−1.

2N2O5 ⟶4NO2+O2

What is the rate of the reaction when [N2O5] = 0.40 M?
