Consider the reaction a → b the rate of the reaction is 1.2 × 10−2 m/s when the concentration of a is 0.11 m. calculate the rate constant if the reaction is first order in a. (give units.)

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
