Question

state and explain of the lechateller principal.​

Answer 1

A principle stating that if a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.

Answer 2

when equilibrium is disturbed by changing the parameter like concentration, pressure, volume and temperature then equilibrium would shift to those direction in which minimise the effect or relief the stress. le chatlier principal which maintain the equilibrium state.

• Concentration -when u increase the concentration of reactant of a reaction, more product will be consumed. According to le chatlier principal, the equilibrium will try to decrease the concentration of reactant by incrising the product so it will shift Toward in forward direction. And vice versa .
• Pressure -when u increase the pressure Of the system eqilibrium would shift to those direction in less number of moles are available. By decreasing pressure.,it will favour in those direction in which more number of moles are available
• Volume -when u increase the volume of system by decreasing the pressure, the equilibrium would favour in the direction where more number of moles are present. And vice versa
• Temperature -for exthormic reaction, heat is released. When u increase the temperature equilibrium will shift toward left because keq value decrease. For exothermic reaction -byincreasing temperature Eqilbrium would shift toward forward direction. Because Keq value increases. Heat is produced in this form.
