If a system at equilibrium is subjected to a change of any one of the factors such as concentration , pressure or temperature, the system adjusts itself in such a way so as to minimise the effect of that change.
For the reaction
`N_(2)(g)+O_(2)(g)hArr2NO(g)`

D

Equilibrium will shift in the forward direction

Text Solution

Verified by Experts

The correct Answer is:
A, B

If a system at equilibrium is subjected to a change of any one of the factors such as concentration , pressure or temperature, the system adjusts itself in such a way so as to minimise the effect of that change. Effect of change in concentration on equilibrium: As we add or remove reactant (or product) the ratio of equilibrium concentratio become 'Q' (reaction quotient) and depending upon. QltK : equilibrium will shift ihn forward direction QgtK equilibrium will shift in backward direction Effect of change in pressure : If a system in equilibrium consists of gases, then the concentrations of all the components can be altered by changing the pressure. When the pressure on the system is increased, then equilibrium will shift in the direction in which there is decrease in number of moles i.e., towards the direction in which there is decrease in volume. Effect of change in pressure on melting point : There are two rypes of solids : Solids whose volume decreases on melting, e.g., ice, diamond, carborundum, magnesium nitride and quartz. Solid (higher volume) hArr Liquid (higher volume) The process of melting is facillitated at high pressure, thus melting point is lowered. Solid whose volume increase on melting, e.g., Fe, Cu, Ag, Au, etc. Solid (lower volume) hArr Liquid (higher volume) In this case the process of melring becomes difficult at high pressure, thuse melting point becomes high. Solubility of substances : When solid substance are dissolved in water, either heat is evolved. for endothermic solubility process solubility increase with increase in temperature. For exothemic solubility decrease with increase in temperature. Solubility of gases in liquids : when a gas dissolves in liquid, there is decreases in voolume. Thus increase of pressure will faavour the dissolution of gas in liquid.

Le Chatelier's Principle If a system at equilibrium is subjected to a change of any one of the factors such as concentration, pressure or temperature, the system adjusts itself in such a way as to nullify the effect of that change. Change of pressure : If a system consists of gases, then the concentration of all the components can be alterd by changing the pressure. To increase the pressure on the system,the volume has to be decreased proportionally. The total number of mols per unit volume will now be more and the equilibrium will shift in the direction in which there is a decrease in number of moles i,e. towards the direction in which there can be decrease in pressure. Effect of pressure on melting point : There are two types of solids: (a) Solids whose volume decreases on melting e.g., ice,diamond carborundum magnesium nitride and quratz. Solids (higher volume) hArr Liquid (lower volume) The process of melting is facilitated at high pressure, thus, melting point is lowerd. (b) Solids whose volume increase on melting e.g.,Fe,Cu,Ag,Au,etc. Solid (lower volume) hArr Liquid (higher volume) In this case the process of melting become difficult at high pressure, thus melting point becomes high. (c) Solubility of substances : When solid substances are dissolved in water, either heat is evolved (exothermic) or heat is absorbed (endothermic). KCI+aqhArrKCI(aq)-heat In such cases, solubility increase with increase in temperature. Consider the case of KOH, when this is dissolved,heat is evolved. KOH+aqhArrKOH(aq)+heat In such cases, solubility decrease with increase in temperature. (d) Solubility of gases in liquids : When a gas dissolves in liquid,there is decrease in volume. Thus increase of pressure will favour the dissolution of gas in liquid.
