Homework Help: Chemistry

Posted by Hannah on Sunday, January 29, 2012 at 5:22pm.

1) Three factors control the rate of evaporation of a liquid: surface area, temperature, and strengths of intermolecular forces. More than one of the statements given described a correct effect. The statements are (1) the larger the surface area, the faster the rate of evaporation of the liquid, (2) the higher the temperature, the faster the rate of evaporation of the liquid, and (3) the stronger the intermolecular attractive forces, the faster the rate of evaporation of the liquid. Which choices are correct?

a) choices 1 and 2
b) choices 1 and 3
c) choices 2 and 3
d) all three choices are valid and describe a correct effect.
e) none of the three choices describe a correct effect.

I think that only statements 2 and 3 are correct. The statement about the surface area is not correct because the higher the density the slower a liquid will evaporate.

Is this correct?
