Equilibrium expression is ![Keq = \frac{[H3O+][HCO3^-]}{[H2CO3]}\\](https://tex.z-dn.net/?f=Keq%20%3D%20%5Cfrac%7B%5BH3O%2B%5D%5BHCO3%5E-%5D%7D%7B%5BH2CO3%5D%7D%5C%5C)
<u>Explanation:</u>
Equilibrium expression is denoted by Keq.
Keq is the equilibrium constant that is defined as the ratio of concentration of products to the concentration of reactants each raised to the power its stoichiometric coefficients.
Example -
aA + bB = cC + dD
So, Keq = conc of product/ conc of reactant
![Keq = \frac{[C]^c [D]^d}{[A]^a [B]^b}](https://tex.z-dn.net/?f=Keq%20%3D%20%5Cfrac%7B%5BC%5D%5Ec%20%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%20%5BB%5D%5Eb%7D)
So from the equation, H₂CO₃+H₂O = H₃O+HCO₃⁻¹
![Keq = \frac{[H3O^+]^1 [HCO3^-]^1}{[H2CO3]^1 [H2O]^1}](https://tex.z-dn.net/?f=Keq%20%3D%20%5Cfrac%7B%5BH3O%5E%2B%5D%5E1%20%5BHCO3%5E-%5D%5E1%7D%7B%5BH2CO3%5D%5E1%20%5BH2O%5D%5E1%7D)
The concentration of pure solid and liquid is considered as 1. Therefore, concentration of H2O is 1.
Thus,
Therefore, Equilibrium expression is
1,2-methylcyclohexane, 1,3-methylcyclohexane, 1,4-methylcyclohexane

The base peak in the mass spectrum of 3-methylpentane has the most plausible value at m/z=57. Hydrocarbons often undergo mass spectroscopic fragmentation at a branch.
<h3>What does the mass spectrometry Mz value mean?</h3>
The horizontal axis in a mass spectrum is stated in units of mass divided by charge number, or m/z. With GCMS, z is usually always 1, hence the mass is frequently determined by the m/z value.
<h3>What is the M Z of the base peak?</h3>
The base peak of the spectrum is defined as the peak with the arbitrary intensity value of 100. The molecular ion, which has a peak at m/z=72, is what determines the molecule's molecular mass.
