Question 1

Given the bond enthalpies CO (707), OO (498), HO (464), and CH (414) in kJ/mol, compute Δ in kJ/mol for: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g).
◦ +618 kJ/mol
◦ +259 kJ/mol
◦ -519 kJ/mol
◦ -618 kJ/mol
◦ -259 kJ/mol

Question 2

Given the bond enthalpies HO (464), ClCl (243), ClO (205), and HCl (431) in kJ/mol, compute Δ in kJ/mol for: H2O(g) + Cl2(g) → HOCl(g) + HCl(g).
◦ -393 kJ/mol
◦ -1100 kJ/mol
◦ +71 kJ/mol
◦ +393 kJ/mol
◦ +1100 kJ/mol
