6283403587 | Le Chateliers Principle | states that a change in the factors that govern the chemical equilibrium of a system will cause the system to respond in a manner that counteracts the change to bring whatever has been changed by the stress(the reaction quotient or equilibrium constant) back into equality with one another. | 0 | |
6283425657 | Way Chemical equilibrium can be disrupted | Change in temperature Change in concentration of reactant or product Change in volume or pressure (Note: catalysts DO NOT affect the equilibrium position, only the speed) | 1 | |
6283454360 | Effect of temperature | ONLY temperature will effect the value of K Must know whether the reaction is exothermic or endothermic | 2 | |
6283531794 | If energy is added to a system....(when it is written as a product) | ......the result would favor the formation of the reactants or the endothermic reaction | 3 | |
6283540549 | If energy is taken away......(when it is written as a product) | ......the result would favor the formation of the products or the exothermic reaction | 4 | |
6283553912 | If energy is added.....(when it is written as a reactant) | .....the result would favor the formation of the products, or endothermic reaction | 5 | |
6283564156 | If energy is taken away.......(when it is written as a reactant) | .....the result would favor the formation of the reactants, or exothermic reaction | 6 | |
6283576694 | Effect of concentration(WILL NOT affect the value of K) | If the concentration of the reactants is decreased, the result would favor the formation of the reactants(REACTANTS SHIFTS BACKWARDS) | 7 | |
6283613528 | If the concentration of the reactants is increased... | ......the result would favor the formation of the products(REACTION SHIFTS FORWARD) | 8 | |
6283623568 | If the concentration of the product is decreased.... | the result of would favor the formation products(REACTION SHIFTS FORWARD) | 9 | |
6283640248 | If the concentration of the product is increased.... | the result would favor the formation of the reactants(REACTION SHIFTS BACKWARD) | 10 | |
6283651570 | Effect of the volume or pressure change(Will not affect the value of K) | Must count the number of mole of gas reactants and gas products to accurately predict the direction | 11 | |
6283679184 | If the volume increases(pressure decreases).... | the system will shift to the side with the greatest number of gas molecules in order to increase the pressure | 12 | |
6284123252 | If the volume decreases(pressure increases).... | ...the system will shift to the side with the least number of gas moles in order to decrease pressure | 13 | |
6284184277 | Observing Shifts in equilibrium | Color change Change in pH | 14 | |
6284194120 | Manipulating Conditions to Optimize Yeild | compromise must be reached in order to achieve decent yields in a cost-effective and timely manner | 15 |
