Fresh day oyewopomohammed, let's solve. Question 1: Evaluate the heat of reaction of CO_(g) + 2H_2(g) → CH_3OH_(g) at 600 \, K and 10.13 \, MPa, H_f = 298 \, K for components given below. To evaluate the heat of reaction at 600 \, K, we need the standard enthalpy of formation ( H_f^) for each component at a reference temperature (typically 298 \, K) and the heat capacity (C_p) data for each component as a function of temperature. The phrase " H_f = 298 \, K" indicates that the standard enthalpy of formation values are provided at 298 \, K. However, the actual values for the "components given below" are missing from the image. Missing Information: Standard enthalpy of formation ( H_f^) for CO_(g), H_2(g), and CH_3OH_(g) at 298 \, K. Heat capacity (C_p) data for CO_(g), H_2(g), and CH_3OH_(g) as a function of temperature (e.g., in a polynomial form like C_p = a + bT + cT^2 + dT^3). Without this specific data, a numerical answer cannot be provided. Below are the general steps to solve this type of problem. Step 1: Calculate the standard enthalpy of reaction at the reference temperature (298 \, K). The standard enthalpy of reaction ( H_rxn^) at 298 \, K is calculated using the standard enthalpies of formation of the products and reactants: H_rxn^(298 \, K) = (_p H_f^)_products - (_r H_f^)_reactants For the given reaction CO_(g) + 2H_2(g) → CH_3OH_(g): H_rxn^(298 \, K) = [1 · H_f^(CH_3OH_(g))] - [1 · H_f^(CO_(g)) + 2 · H_f^(H_2(g))] Note: The standard enthalpy of formation for an element in its standard state, like H_2(g), is 0 \, kJ/mol. Step 2: Calculate the change in heat capacity for the reaction ( C_p). The change in heat capacity for the reaction is the sum of the heat capacities of the products minus the sum of the heat capacities of the reactants, considering their stoichiometric coefficients: C_p = (_p C_p)_products - (_r C_p)_reactants For the reaction: C_p = [1 · C_p(CH_3OH_(g))] - [1 · C_p(CO_(g)) + 2 · C_p(H_2(g))] If the C_p values are given as a polynomial in temperature (e.g., C_p = a + bT + cT^2 + dT^3), then C_p will also be a polynomial in T: C_p = a + b T + c T^2 + d T^3 where a = a_CH_3OH - (a_CO + 2a_H_2), and similarly for b, c, d. Step 3: Adjust the enthalpy of reaction from 298 \, K to 600 \, K using Kirchhoff's Law. The enthalpy of reaction at a different temperature T_2 can be calculated from the enthalpy of reaction at T_1 using the integral of C_p over the temperature range: H_rxn(T_2) = H_rxn(T_1) + _T_1^T_2 C_p \, dT In this problem, T_1 = 298 \, K and T_2 = 600 \, K. If C_p is a polynomial
