Document Summary

Coupled reactions have opposite signs of gsys. This is because one of the two coupled reactions is spontaneous, so it can occur independently; the other requires the energy produced by the first to occur. These reactions are quite common in nature (example of coupled reactions?) G= h ts; the temperature will be 298 k (we know because the superscript indicates that this happens in standard conditions) Increasing temperature will increase the rate of both the forward and reverse reactions due to increase number of collisions and extra energy available as heat. Increase collision energy but does not increase favorability of orientation. Stressors do not affect k but it affects q. This is endothermic to we know that h is positive. We see that solid turns into aqueous so s is positive. This mean that this reaction is only spontaneous at high temperatures (g= h ts) Molecules increase their types of motion: vibration, rotation, translation.
