The condensation of any gas to a liquid is expected to have:
(1) `Delta H=-ve,Delta S=+ve`
(2) `Delta H=+ve,Delta S=+ve`
(3) `Delta H=-ve,Delta S=-ve`
(4) `Delta H=+ve,Delta S=-ve`

Which of the following conditions may lead to a non-spontaneous change? a. DeltaH " and "DeltaS " both "+ve b. DeltaH=-ve,DeltaS=+ve c. DeltaH=+ve,DeltaS=-ve d. DeltaH=-ve,DeltaS=-ve

Correct relation for isothermal reversible expansion of an ideal gas is Delta U=0 , Delta S=0 , Delta G=-T Delta S , Delta H=0

For which of the following change Delta H!=Delta U ?

In which of the following Delta H = Delta U ?

Delta E and Delta H both are zero in

Comment on the spontaneity of a process when Delta H gt 0, T Delta S lt 0

Identify the reaction for which Delta H != Delta E

If Delta denotes the area of any triangle and s its semiperimeter, prove that Delta is less than S^2/4

A vertical line passing through the point (h, 0) intersects the ellipse x^2/4+y^2/3=1 at the points P and Q .Let the tangents to the ellipse at P and Q meet at R . If Delta (h) Area of triangle DeltaPQR , and Delta_1 = max_(1/2<=h<=1)Delta(h) and Delta_2 = min_(1/2<=h<=1) Delta (h) Then 8/sqrt5 Delta_1-8Delta_2

For the reaction, A(s) + 3B(g) rarr 4C(g) + d(l) Delta H and Delta U are related as :
