Answer 1

Answer #1

Vapour pressure is function of temperature only so after the equilibrium is established vapour pressure is same 23.8 as temperature is maintained same

At intial point when volume is increased pressure will drop to lower value but this will further increase rate of evaporation resulting into same vapour pressure

In a closed container, one gram of water (1 cm) is boiled under constant pressure of 1 atm (1.013 10Pa) until it changes into steam. The heat of vaporization at this pressure is Lv = 2.256 x 106J/kg = 2256 J/g. Assume that water vapor behaves like an ideal gas. The temperature of the steam is 373 K, number of moles of water vapor n = 0.0546 (g mol), the ideal gas constant R = 82.057 (cm3.atm/g mol-K). (a) How...
