*The decomposition of acetaldehyde is a first order reaction with a specific rate constant of 6.0 X 10^-1 / min.
CH₃CHO --> CH₄ + CO
1. Calculate the initial rate when the concentration of acetaldehyde is 0.80M.
2. Calculate the time needed for the concentration of the acetaldehyde to decrease by 0.05 M from an initial concentration of 1.20 M.
