In organic chemistry acetone is one of the most important solvents, used to dissolve everything from waxes and fats to airplane nail polish and glue. At high temperatures, it decomposes in a first-order process to methane and ketene (CH2=C=O). At 600°C, the rate constant is 8.7x10-3 s-1.

2. Explain how much time is needed for 66% of a sample of acetone to decompose?
