| what happens if you decrease the conc of the products | the system tries to increase it again by reducing the amount of reactants |
| when is a reversible reaction in equilibrium | when the forward reaction is going at the exact same rate as the backwards reaction, theres no overall effect as reactants and products have reached a balance and won't change |
| where can equilibrium only take place | in a closed system so no reactants or products can escape |
| what's the forward reaction if the backward reaction is endothermic | exothermic |
| what happens if you heat blue hydrated copper(ii) sulphate crystals | it drives the water off and leaves white anhydrous copper(ii) sulphate powder, its endothermic |
| what happens if u add water to white anhydrous copper(ii) powder | you get blue hydrated copper(ii) sulfate crystals, exothermic |
| what is le chateliers principle | if you change the conditions of a reversible reaction at equilibrium, the system will try to counteract change and it can be used to predict the effect of any changes you make to a reaction system |
| what will happen if you decrease the temperature of a reaction | the equilibrium will move in the exothermic direction to produce more heat so you'll get more products for the exothermic reaction and less products for the endothermic reaction |
| what happens if you increase the temperature of a reaction | the equilibrium will shift to the endothermic direction to try to decrease temperature so you'll get more products for the endothermic reaction and less for the exothermic reaction |
| changing the pressure only effects what in equilibrium | gases (make sure to check state symbols) |
| what happens if you increase the pressure of a reaction | the equilibrium shifts to the side with the fewest gas molecules to reduce pressure |
| what happens if you decrease the pressure of a reaction | the equilibrium will shift to where theres more molecules of gas to increase the pressure |
| what happens if you change the concentration of a reaction | the system will no longer be in equilibrium so the system responds to bring itself back to equilibrium |
| what happens if you increase the conc of the reactants | the system tries to decrease it by making more products |
| what happens if you decrease the conc of the products | the system tries to increase it again by reducing the amount of reactants |
| what happens if you decrease the conc of the products | the system tries to increase it again by reducing the amount of reactants |
