The reaction between hydrogen and oxygen to form water is given as: \( 2H_2 + O_2 \rightarrow 2H_2O \). If 4 moles of hydrogen react with excess oxygen, how many moles of water will be formed?
Given the following information about a chemical reaction: - Change in Gibbs free energy (\( \Delta G \)) = \( -100 \, \text{kJ/mol} \)
- Change in enthalpy (\( \Delta H \)) = \( -150 \, \text{kJ/mol} \)
- Temperature (\( T \)) = \( 298 \, \text{K} \) Calculate the change in entropy (\( \Delta S \)) for the reaction. The relationship between Gibbs free energy (\( \Delta G \)), enthalpy (\( \Delta H \)), and entropy (\( \Delta S \)) is given by the equation: \[ \Delta G = \Delta H - T\Delta S \]
