The easiest way to think about this is as the 'law of opposites' TemperatureExothermim reactions: If temp is increased then the reaction moves in the direction to reduce this rise of temp by shifti...

As you progress down the group:- Atomic radius increases, therefore there is more electron shielding.- There is an increase in the nuclear charge, however it is outweighed by the increase in shielding.- I...

Le Châtelier's principle is that when a system has reached a dynamic equilibrium the position of equilbrium will move to resist any change that is imposed on it.
