Cis/Trans Isomerism
Type of E/Z isomerism where there is a non-hydrogen group and a hydrogen attached to each carbon of a C=C bond.
6 of 11
Equilibrium existing in a closed system when the rate of the forward reaction is equal to the rate of the reverse reaction.
Dynamic Equilibrium

Endothermic
A reaction which takes in heat from its surroundings (ΔH is positive).
8 of 11
E/Z Isomerism
Type of stereoisomerism whereby different groups attached to each carbon of a C=C bond are arranged differently in space due to restricted rotation of the C=C bond.
