state and expalin le-chateller's principle .which factor can alter the equalibrium state
Answers
Explanation:
Le Chatelier's principle states that is there is a change in concentration, pressure or temperature, the equilibrium will move in order to counteract the change.
Firstly temerature - in an reversible reaction, one reaction will be exothermic (i.e. gives out heat, to indicate bond making) and the other reaction will be endothermic (requires heat to be taken in, and is bond breaking). If there is for example, a rise in temperature, the equilibrium will shift in the endothermic direction in order to oppose the change in temperature. This is because if there is an increase in temperature, the system will be disturbed and so will produce a change in order for the equilbirum to return back to normal. So if there is an increase in temperature, the eqilibrium will shift in the endothermic direction so that more heat is taken in (and removed). Similarly, if there is a decrease in temperature, the equilibrium will shift in the exothermive direction to generate more heat. You can always tell which direction is exothermic as when a reversible reaction is written, the enthalpy change will be quoted by the side. If the enthalpy change is negative it means the forward reaction is exothermic, and so the backward reaction will be endothermic. If the enthalpy chnage is positive, the forward reaction will be endothermic, and backward reaction exothermic
