Answer:
a. H20,because it experiences hydrogen bonding.
The experimental evidence that you could provide that <span> the product isolated is 1-bromobutane would be the changes that happens that are observable by the naked eye. Hope this helps. Have a nice day. Feel free to ask more questions.</span>
<u>Answer:</u> The value of
for the given chemical reaction is 0.1415
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as 
For a general chemical reaction:

The expression for
is written as:

For the given chemical equation:

The expression for
for the following equation is:

We are given:

Putting values in above equation, we get:

The value of
for the given chemical reaction is 0.1415
