What is the free energy change `triangleG` when 1.0 mole of water at `100^@C` and 1 atm pressure is converted into steam at `100^@C` and 1 atm pressure?

A

540 Cal

B

`-9800` Cal

C

9800 Cal

D

0 Cal

Text Solution

Verified by Experts

The correct Answer is:
D

`underset("Water")(H_(2)O_((l)))overset(100^(@)C)underset("1 atm")hArr underset("Steam")(H_(2)O_((g)))`
At equilibrium `Delta G = 0`

Calculate the work done (w) and internal energy change ( DeltaU ), when one mole of water at 100^@C vaporises against an atmospheric pressure of 1 atm assuming ideal gas behaviour. Heat of vapourisation of water at 100^@C is 1020 cal mol^(-1) .

The average free path at 1 atm pressure is L . What should be its value at 5 atm pressure?

A sample of 0.5 g water at 100°C and 1 atm pressure requires 270 cal heat energy to convert to steam at 100°C. If at the same pressure, volume of the steam produced is 835.5 cc then change in internal energy of the sample is (1 cal = 4.2 J, 1 atm 10^5 N/m^2 )

Calculate the percentage of free volume available in 1 mole gaseous water at 1 atm pressure and 373 K.
