question 89

Multiple Choice

Calculate the standard reaction enthalpy for the following reaction. CH₄(g) + H₂O(g)  CO(g) + 3H₂(g)
Given:
2H₂(g) + CO(g)  CH₃OH(l)
H° = 128.3 kJmol^1
2CH₄(g) + O₂(g)  2CH₃OH(l)
H° = 328.1 kJmol^1
2H₂(g) + O₂(g)  2H₂O(g)
H° = 483.6 kJmol^1

• A)+155.5 kJ  mol ^{ 1}
• B)+ 216 kJ  mol ^{ 1}
• C)+412.1 kJ  mol ^{ 1}
• D)+42.0 kJ  mol ^{ 1}
• E)+206.1 kJ  mol ^{ 1}
