question 37

Multiple Choice

Given H₂(g) + (1/2) O₂(g) $\rarr$ H₂O(l) , $\Delta$ H ^$\circ$ = -286 kJ/mol, determine the standard enthalpy change for the reaction 2H₂O(l) $\rarr$ 2H₂(g) + O₂(g) .

• A)(\(\Delta\)H^\(\circ\)) = -286 kJ/mol
• B)(\(\Delta\)H^\(\circ\)) = +286 kJ/mol
• C)(\(\Delta\)H^\(\circ\)) = -572 kJ/mol
• D)(\(\Delta\)H^\(\circ\)) = +572 kJ/mol
• E)(\(\Delta\)H^\(\circ\)) = -143 kJ/mol
