Question

Question 8 The vapor pressure of a liquid increases linearly with increasing temperature increases nonlinearly with increasing temperature decreases linearly with increasing temperature decreases nonlinearly with increasing temperature is totally unrelated to its molecular structure

Answer 1

Answer question 8: Correct Answer is Vapour pressure of a liquid increases nonlinearly with increasing temperature can write ta niha) vapour Explanation From clausius clapeyron egun we infp) = det or P2 = P, e AW (177) - l T, Tz) 0 where, P, and Pe are initial & final pressure respectively Ti and Tz are initial and final temp, respectively 4H → Enthalpy Change (Moler enthalpy) R » gas const. from equino © it is crear that vapour pressure is exponentially related to the temperature, so it is non linearly increases with increasing temp. on the other hand with increasing temp. vapour pressure increases, because more molecule will go to the vapour State from liquid State due to increase of temp. so due to more molecule in vapoure phase, the pressure will be more. and explanation the other options Due to are above reason incorrect.
