Check Explanation
Explanation:
The Heat of reaction for the forward reaction is defined as the amount of heat given off or absorbed while the forward reaction is taking place. Mathematically, the heat of reaction for the forward reaction is given as the heat content/heat of formation/Enthalpies of the reaction's products minus the heat content/heat of formation/Enthalpies of the reaction's reactants.
ΔH°run = H°(products) - H°(reactants)
When the heat of reaction is negative, the reaction is said to be exothermic and when it is positive, the reaction is said to be endothermic.

<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
