reversible reaction

• reversible reactions go backwards and forwards
• if the forward reaction is endo then backwards will be exo
• if forward is exo then it wants a low temperature in surroundings
• if backwards is endo then it will want a high temp
• equillibrium is reached when rate of forward and reverse reaction is the same
• equilibrium has to be in a closed system
• at equilibrium, the amount of particles does not need to be the same
• le chateliers principle states if temperature increases equilibrium favours endo as temperature needs to decrease
• le chateliers principle states if temperature decreases, equilibrium will favour exo as temp needs to increase
• la chateliers principle states that if concentration of reactants increases then equilibrium will shift right
• le chateliers principle states that an increase in concentration of products causes equilibrium to shift left
