For an ideal solution,`Delta_(mix)V` is ……….and `Delta_(mix)H` is ………. .

A solution having `Delta_(mix)H`=+ve will exhibit ……….deviation from ideal behaviour.

For a non-ideal solution, `Delta_(mix)V` and `Delta_(mix)H` are zero.

Assertion:In an ideal solution , `Delta_"mix"H` is zero
Reason :In an ideal solution , A-B interactions are lower than A-A and B-B interactions.

The mathematical expression for the standard enthalpy of sublimation is given by _________ . (Here, Delta_("sub")H^@=Delta_("sublimation")H^@, Delta_("fus")H^@=Delta_(fusion)H^@,Delta_(vap)H^@=Delta_("vaporization")H^@,=Delta_(comb)H^@=Delta_(combustion)H^@,Delta_(diss)H^@=Delta_(dissociation)H^@)

The enthalpy of mixing `(Delta_(mix) H)` and volume of mixing `(Delta_(mix) V)` of pure components to form the solution are :

Mention th.e enthalpy of mixing (Delta_(mix)) value to form an ideal solution.

वक्तव्य I कथन आदर्श विलयन के लिए `DeltaH_("मिश्रण")` तथा `DeltaV_("मिश्रण")` शून्य होते हैं।
आदर्श विलयन में A-B अन्योन्य क्रिया A-A तथा B- B अन्योन्य क्रिया के समान होती है।

Mention the enthalpy of mixing `(Delta_("mix")H)` value to form an ideal solution. 

Fdr an ideal solution of liquid in liquid give two expressions for enthalpy of mixing (∆_(mix)H) and volume of mixing (∆_(mix)V).
