Why do branch chained isomers have lower boiling point than straight chain equivalents?

As branching increases the boiling point decreases because there are fewer points of contact. This also means van der Waals forces are weaker in branch chained isomers and thus less energy is required to ove...

What happens when a reversible reaction is at equilibrium?

A reversible reaction is one where the reaction can occur both ways. Therefore, in a closed system where nothing can escape, some products made will always react in the reverse direction to make the reactant...
