Answer:

The increasing order of boiling point is HCl, C3H6, C2H5OH.

Explanation:

The increasing order of boiling point is:

HCl = -85°C

C3H6 = -47.6°C

C2H5OH = 78.5°C

The boiling point is directly proportional to the strength of inter-molecular forces.

HCl molecule has weak, dipole-dipole and Van der waal's forces, thus it has smallest boiling point.

C3H6 has the second less boiling point owing to the presence of one double bond.

C2H5OH has the highest boiling point due to strong hydrogen bonding.

The answer is HCl, C3H6 and C2H5OH. Hydrochloric acid has the lowest boiling point among the three choices since it only has weak dipole-dipole and Van der Waal's forces between molecules which are much weaker than the forces of attraction present in propane and ethanol. Ethanol has the highest since the hydrogen bonding present in ethanol make it hard to break the bonds.

What are the units of k in the following rate law?
Ludmilka [50]

Answer:

B. \frac{1}{M^{2} s }

Explanation:

The unit for rate is M/s while the unit for each molecule should be M. You can find the unit for k by putting the units for rate and the molecules into the equation

rate= k{X][Y]

M/s= k * M^{2} * M^{1}

k= (M/s) / (M^{3})

k= \frac{1}{M^{2} s }

You can also use this predetermined formula to solve this problem faster: k= \frac{M^{1-n} }{s }

Where n is the number of molecule. There are 3 molecule(2X and 1Y) so n=3, so

k= \frac{M^{1-n} }{s }

k= \frac{M^{1-3} }{s }= \frac{m^{-2}}{s}= \frac{1}{M^{2} s }
