Assertion: The m.pt. of ice is lowered on increasing the pressure, whereas m.pt. of solids other than ice is raised upon increasing pressure.
Reason: Ice shows H-bonding and leads to three dimensional solid of more volume.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Ice `hArr` Water
`V_(s) gt V_(w)`
Thus, forward reaction occurs on increasing pressure, i.e., more ice will melt or m.pt.is lowered.
Solid `hArr` Liquid
`V_(s) lt V_(L)`
Thus, more solid will be formed on increasing pressure.

Assertion : The melting point of ice decreases with increase of pressure Reason : Ice contract on melting.

Assertion: The melting point of solid (except ice) increases with increase in pressure. Reason: An increasion in pressure favours the change where volume decreases.

The increase of pressure on ice water system at constant temperature will lead to :

Assertion : For the physical equilibrium , Ice hArr wate On increasing temperature and increasing pressure more of water will form. Reason : Since the forward reaction is endothermic in nature and the volume of water is lesser than the volume of ice.

A : For equilibrium ice hArr water on increasing temperature and pressure more of water will form. R: Forward reaction is endothermic and volume decreases on product side.

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. For the reaction (1)/(2)N_(2)(g)+(1)/(2)O_(2)(g)hArrNO(g) If pressure is increased by reducing the volume of the container then:
