Text Solution

AI Generated Solution

To solve the problem, we need to calculate the energy requirement for the production of 0.36 g of glucose (C₆H₁₂O₆) by the reverse reaction of its combustion. The combustion reaction is given as: \[ C_6H_{12}O_6 (s) + 6O_2 (g) \rightarrow 6CO_2 (g) + 6H_2O (g) \] \[ \Delta_c H = -2840 \, \text{kJ/mol} \] ### Step-by-Step Solution: **Step 1: Determine the molar mass of glucose (C₆H₁₂O₆).** ...
