please help thanks

At 25C, the following heats of reaction are known: 2CIF(g)+O2(g)Cl2O(g)+F2O2ClF3(g)+2O2(g)Cl2O(g)+3F2O(g)2F2(g)+O2(g)2F2O(g)Hixn=167.4kJ/molHixn=341.4kJ/molHinn=43.4kJ/mol At the same temperature, use Hess's law to calculate Hnn0 for the reaction: CIF(g)+F2(g)ClF3(g) 217.5kJ/mol 130.2kJ/mol 217.5kJ/mol 108.7kJ/mol 465.4kJ/mol
