How does an increase in reactant concentration affect the rate of reaction?
Trava [24]
Option A is the correct option.

In terms of the collision theory, increasing the concentration of a reactant increases in the number of collisions between the reacting species per second and therefore increases the reaction rate.

Compare how entropy changes for the following two systems
bazaltina [42]

Remember the fact

Randomness follows the order

  • Gas>Liquid>Solid

#System A

As solid particles are dissolved in water their randomness increases so entropy increases

#System B

Gas is converted to liquid so entropy decreases as randomness decreases

Propylamine and trimethylamine have the same molecular formula, C 3 H 9 N, but different structures.
laiz [17]
The structure of propylamine is pretty linear CH3-CH2 - CH2 - NH2.

The structur of trimethylamine is completely branched: a atom of N surroundeb by three CH3- radicals.

As theory predicts, in absence of other factors, longer chains have higher intermolecular forces  (London forces) than branched compounds. So we must expect that propylamine has higher boiling point methyleamine.

You can verify that prediction with the literature. I did it: propylamine boiling point is 47-51°C while methylamine boiling point is 3 - 7°C.
