Reactions: A balanced chemical reaction equation shows the mole relationships of reactants and products, while a chemical reaction equation gives the reactants and products. The amount of energy involved in the reaction is frequently stated. Reaction stoichiometry is the study of the quantitative aspects of chemical reactions.

Considering the given information:

Given isotopic equilibrium

$$\begin{gathered} CO\left(g\right)+2H_2\left(g\right)鈬�C{H}_{3}OH\left(l\right) \\ 鈭�H{掳}_{rxm}=-128kJ/mol \\ {K}_P=2.25脳{10}^{4}at{T}_1=298K \\ {K}_P=?at{T}_2=0掳C \end{gathered}$$

We'll start by converting the temperature value from $掳C$to K:

$$\begin{gathered} T=0掳C+273.15 \\ T=273.15K \end{gathered}$$

We will use Van't Hoff equation to calculate $K_P$at $T_2=0掳C$:

$$\begin{gathered} In\frac{K_2}{K_1}=-\frac{鈭�H_{rxm}^{掳}}{R}\left[\frac{1}{T_2}-\frac{1}{T_1}\right] \\ In\frac{K_P}{2.25脳{10}^4}=-\frac{-128脳{10}^{3}J/mol}{8.314J/mol脳K}\left[\frac{1}{273.15}-\frac{1}{298K}\right] \\ {K}_P=2.55脳{10}^6 \end{gathered}$$

Therefore, the required value is $2.55脳{10}^6$.
