Even if two samples of matter have the same temperature, it does not necessarily mean they have the same total energy. The more particles a substance has at a given temperature, the more thermal energy it has.

The question is incorrect, nitration of methylbenzoate occurs at 3 position to get, methyl 3-nitrobenzoate.
This is because, in present reaction the reactant i.e. methylbenzoate, has low electron density at m-position.
Due to this, NO2+ prefentially attaches m-position to form methyl 3-nitro benzoate as the product.
A detailed reaction mechanism for formation of product is provided below.

Answer:</h3>
pH = 8.66
<h3>
Explanation:</h3>
- The pH refers to the acidity or alkalinity of a solution.
- It is calculated by getting the negative logarithm of Hydrogen ions concentration.
In this case;
we are given [OH⁻] as 4.6 x 10^-6 M
We are required to calculate the pH
We need to know that;
pH + pOH = 14
pOH = -log[OH⁻]
To get the pH we can calculate the pOH first,
pOH = -log[4.6 x 10^-6 M]
= 5.34
but, pH + pOH = 14
Therefore, pH = 14 - pOH
= 14 - 5.34
= 8.66
Therefore, the pH of the solution is 8.66
