It is found that a gas undergoes a zero-order decomposition reaction in the presence of a nickel catalyst. If the rate constant for this reaction is 8.1 x 10-2 mol/ (l*s), how long will it take for the concentration of the gas to change from an initial concentration of .1M to 1.0 x 10-2 M?
I have been use [A]t = -kt + [A]o
I keep getting [1.0 x 10-2 M] = -8.1 x 10-2 x t + [.1M]
1.0 x 10-2 M / -8.1 x 10-2 - .1M = .02345 Book says the answer is 1.1s, not sure what I am doing wrong.
