Two tons of water is pumped into a tank 15 ft. high in 5 minutes. Determine the power output of the pump (Note: One ton is equal to 2,000 lb, and remember to convert the minutes
to seconds)

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

Under which circumstances are kp and kc equal for the reaction aa(g)+bb(g)⇌cc(g)+dd(g)?
