For a liquid the vapour pressure is given by `"log"_(10) P = (-400)/(T) + 10`. Vapour pressure of the liquid is `10^(x) mm` Hg. The value of x will be-----

Text Solution

Verified by Experts

The correct Answer is:
9
`log_(10) P = - (400)/(T) + 10 = - (400)/(400) + 10 = 9`
`P = 10^(@) mm Hg x = 9`
