Equimolal solutions in the same solvent have
(a) same boiling point but different freezing point
(b) same freezing point but different boiling point
(c) same boiling and same freezing points
(d) different boiling and different freezing points
(c) : According to Raoult’s law equimolal solutions of all the substances in the same solvent will show equal elevation in boiling points as well as equal depression in freezing point.
(i) (a) The order of increasing hydrogen ion concentration is C < A < B. Higher the pH value, lower is the hydrogen ion concentration.
(b) B is most acidic as...
(a) : Elevation in boiling point is a colligative property which depends upon the number of solute particles.
Greater the number of solute particles in a solution, higher the extent of...
(b) : For endothermic reaction, ΔH = +ve
Now, ΔG = ΔH – TΔS
For nonspontaneous
reaction, ΔG should be positive
Now ΔG is positive at low temperature if ΔH is positive.
ΔG is negative...
Total mass of solution = 150 + 150 = 300 g
Q = Total heat produced
= 300 x (28.77-25.35) cal
=300 x 3.42= 1026 cal
Heat of neutralization = Q/150 x 1000 x...
(b) For endothermic reaction, ΔH=+ve. Now, ΔG=ΔH-TΔS
ΔG will be +ve when ΔH and ΔS both are +ve and temperature is low so that ΔH> (-TΔS). ΔG will be –ve When...
