Consider the following reaction at equilibrium. What effect will decreasing the temperature have on the system? CO2(g) + 2 H2O(l) ↔ CH4(g) + 2 O2(g) ΔH° = +890 kJ

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.
