Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
the total number of molecules in each phase stays constant
the reaction would shift to favor the side with the most moles of gas
poh=14-ph
Kb = [CH3NH3 +] [OH-] / [CH3NH2]
A measure of the acidity of the solution
as concentration increase the faster the rate of reaction and vice versa
