Answer:
The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature
Explanation:
Given
Required
Interpret
Multiply both sides by T1
Divide both sides by V1
This can be rewritten as:
In the above expression; k is a constant of proportionality.
So, the equation can be written as variation as follows:
To interpret:
<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>

Answer:
Only gives spontaneous reaction.
Explanation:
A redox reaction will be spontaneous if standard reduction potential () of the reaction is positive. Because it leads to negative standard gibbs free energy change (
), which is a thermodynamic condition for spontaneity of a reaction.
Where and
represents standard reduction potential of reduction half cell and standard reduction potential of oxidation half cell.
(1) Oxidation: ;
Reduction: ;
So,
Hence this pair will give spontaneous reaction.
(2) Similarly as above,
Hence this pair will give non-spontaneous reaction.
(3) Similarly as above,
Hence this pair will give non-spontaneous reaction.
(4) Similarly as above,
Hence this pair will give non-spontaneous reaction.
