The following processes occur in an internal combustion engine. For which one is the entropy change negative?
Compression of the gasoline/air mixture in a pistonIgnition: 2 C8H18 (octane) (g) + 25 O2 (g) --> 16 CO2 (g) + 18 H2O (g)Expansion of hot CO2 (g) and H2O (g) in a pistonRelease of CO2 (g) and H2O (g) into the airAll of these have a positive entropy change.
You are in a labratory and need to make 90 mL of a solution that is 2 micrograms Eb per 0.1 mL safflower oil. outline the steps and calculations.
