Answer:
The half life time of first order reaction is 1.3 sec
Explanation:
Given:
First order rate constant

Initial concentration
M
From the formula of first order half life time,

So half life time is given by,

sec
Therefore, the half life time of first order reaction is 1.3 sec.

Answer:
to collect liquid ethanol and leave ethene as a gas because ethanol has hydrogen bonds
Explanation:
The chemist would be lesser than the temperature of the mixture as to collect the liquid ethanol and then leave ethene as a gas since the ethanol is a bond that should be hydrogen. Also -OH that available in the ethanol would be responsible for the hydrogen bonds also it is the main and significant molecular forice
So as per the given situation the above represent the answer
