a) Thisis incorrect. As temperature increases, molecules have more energy to escape into the gas pahse.
b) This is true (i think). An equilibrium of any kind results when the forward rate is equal to the reverse rate.
c) This is correct. Look up Clayperon equation (the general relation from which most other vapor pressure equations come from) to see that vapor pressure is dependent on temperature.
d)This is true. Different interactions between different molecules will cause different substances to have different boiling points.
form of. Partial tension refers to how lots someone gas is affecting the over all tension. interior the least confusing words, the partial tension is the mole fraction interior the vapour section situations the strain (whether it is a desirable gas). So in case you communicate approximately someone ingredient via itself to have a tension of 60kPa, then it is partial tension is 60kPa whether the entire tension with different gases jumbled together bigger. Vapor tension refers back to the strain of the vapour ingredient. Say you have water at room temperature. Water at this temperature is a liquid, yet some water will nevertheless evaporate into the vapour section. the quantity of water interior the vapour section will strengthen till the partial tension of the water interior the vapour section is comparable to its vapour tension. At this factor the quantity of water interior the vapour section won't exchange.
