Reversible Reactions Flashcards
Chemistry
Equilibrium
Concentration don’t change: the rate of the forward reaction is equal to the rate of the reverse reaction, takes place in a ‘closed system’
Increased temperature favours
the ____________ reaction
Endothermic
Increased pressure (gases only) favours the _______________
Reaction producing fewer molecules/moles
Increased concentration of reactants favours _________ reaction and produces more products
Forward
Catalyst
Increases rate of reaction by providing an alternative pathway for the reaction which has a lower activation energy
Exothermic
Negative energy change
Endothermic
Positive energy change
Le Chatelier’s Principle
If a factor affecting the position of equilibrium is altered, the position of the equilibrium shifts to oppose the effect of the change
