The vapour pressure of water at 25°C is ...

The vapour pressure of water at 25°C is 0.0313 atm. Calculate the values of `K_(p)` and Kc at 25°C for the equilibrium `H_(2)O(1)hArr H_(2)O(g)`.

A

`1.28 xx 10^(-3)` and 0.03 13 atm respectively

B

0.0313 and `1.28 xx 10^(-3)` atm respectively

C

`1.28 xx 10^(-3) and 1.28 xx 10^(-3)` atm respectively

D

0.0313 and 0.0313 atm respectively

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(p)=P_(H_(2)O) (g), K_(p)=0.0313atm`
`K_(p)=K_(c) (RT)^(1)`
