<u>Answer:</u> The value of 
for the reaction at 550.3 K is 247.83
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For a general chemical reaction:
The expression for is written as:
![K_{c}=\frac{[C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=K_%7Bc%7D%3D%5Cfrac%7B%5BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D)
The chemical equation for the production of methanol follows:
The expression of for above equation follows:
![K_c=\frac{[CH_3OH]}{[CO][H_2]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCH_3OH%5D%7D%7B%5BCO%5D%5BH_2%5D%5E2%7D)
We are given:
![[CH_3OH]=0.0401mol/L](https://tex.z-dn.net/?f=%5BCH_3OH%5D%3D0.0401mol%2FL)
![[CO]=0.02722mol/L](https://tex.z-dn.net/?f=%5BCO%5D%3D0.02722mol%2FL)
![[H_2]=0.07710mol/L](https://tex.z-dn.net/?f=%5BH_2%5D%3D0.07710mol%2FL)
Putting values in above equation, we get:
Hence, the value of for the reaction at 550.3 K is 247.83

Single Replacement
<h3>Further explanation</h3>
Given
Reaction
Mg(s) + 2 HCl(aq) → MgCl2 (aq) + H2 (g)
Required
Type of reaction
Solution
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Not all of these reactions can occur. We can use the activity series(the Volta series)
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger the reductor)
