The correct answers are :
Changing the volume of the system.
Changing the temperature of the system.
Equilibrium will remain unaffected if the concentration of products and reactants are kept the same, and the temperature of the system is kept constant.
As the system is closed, we cannot add or remove products or reactants.
Change in temperature will shift the chemical equilibrium towards the reactant or product depending on whether the reaction is exothermic or endothermic.
Also change in volume will shift the chemical equilibrium of a chemical reaction if the reactants or products or both are gases.
Answer : The value of ΔG expressed in terms of F is, -1 F
Explanation :
First we have to calculate the standard electrode potential of the cell.

or,


Now we have to calculate the standard cell potential.
Formula used :

where,
= Gibbs free energy = ?
n = number of electrons = 2
F = Faraday constant
= standard e.m.f of cell = +0.5 V
Now put all the given values in this formula, we get the Gibbs free energy.


Therefore, the value of ΔG expressed in terms of F is, -1 F
Here first we will identify the number of significant figures in the given two dimensions
2.3mm : there are two significant numbers
8.00mm: there are three significant numbers
so we will report the answer to minimum number of significant number , which is two
the answer is 18.4
We will report it to be 18 mm^2
The inverse proportion is PV = k
We can write the equation as <em>P</em> = k/<em>V</em> or <em>P</em> ∝ 1/<em>V</em>. Thus, <em>P</em> and <em>V</em> are <em>inversely related</em>.
We can rewrite <em>V</em>= T/k as <em>V</em> = k<em>T</em> or <em>V</em> ∝ <em>T</em>. Thus,<em> V</em> is <em>directly proportiona</em>l to <em>T</em>
.
<em>F</em> = -k<em>x</em>² is <em>neither a direct nor an invers</em>e relation.
<em>y</em> = k<em>x</em> – 8 is a linear relation, but it is <em>not a direct proportion</em> because of the “-8” term.
