Explanation:
The rate of the reaction increases when a catalyst has been added to the reaction mixture by e) providing a new mechanism for the reaction to procced by
Catalyst, in chemistry, a substance that speeds up a reaction without itself being consumed. Enzymes are natural catalysts responsible for many important biochemical reactions.
Most solid catalysts are oxides, sulfides, halides of metals or metallic elements, and metalloid elements boron, aluminum and silicon. Gas and liquid catalysts are usually used in pure form or in combination with suitable carriers or solvents. Solid catalysts are usually dispersed in another material known as a catalyst support.

Explanation:
Answer:
a) The molecule is always polar.
Explanation:
The molecule is always polar because of two reasons:
- all the bonds are polar due to the difference in electronegativity between carbon and hydrogen & carbon and chlorine.
AND IMPORTANTLY
- The molecule is asymmetrical meaning that the dipoles cannot cancel each other out (like they do in methane or carbon dioxide for example) so the net effect is a polar molecule.
To estimate for the minimum temperature of a daily forecast of low temperature, the first estimate would be the dew point temperature approximately an hour before the daily high temperature is reached. I hope this helps you on your assignment.
