Changes

: When the [[Reaction Mixture|reaction mixture]] is initially added to a [[Reaction Vessel|reaction vessel]] the [[Rate of Reaction|rate]] of the forward [[Chemical Reaction|reaction]] is high. As the [[Chemical Reaction|reaction]] progresses the [[concentration]] of original [[reactant]]s decreases, slowing [[Rate of Reaction|rate of reaction]]. Meanwhile the [[concentration]] of [[product]]s increases, which increases the rate of the back [[Chemical Reaction|reaction]]. Once the two [[Rate of Reaction|rates of reaction]] are equal then the [[Reaction Mixture|reaction mixture]] is in [[Dynamic Equilibrium|dynamic equilibrium]].
