Calculate DeltaH when 2 moles of solid benzoic acid undergo complete combustion at 300 K if C_(6)H_(5)COOH(s)+(15)/(2)O_(2)(g)to7CO_(2)(g)+3H_(2)O(l) DeltaU_(reaction)=-750 kJ// mole

The value of DeltaH-DeltaU when 2 moles of solid benzoic acid undergoes combustion at 300 K is given by :

Consider the reaction at 300K C_(6)H_(6)(l)+(15)/(2)O_(2)(g)rarr 6CO_(2)(g)+3H_(2)O(l),DeltaH=-3271 kJ What is DeltaU for the combustion of 1.5 mole of benzene at 27^(@)C ?

Compounds with carbon-carbon double bond, such as ethylene, C_(2)H_(4) , add hydrogen in a reaction called hydrogenation. C_(2)H_(4)(g)+H_(2)(g) rarr C_(2)H_(6)(g) Calculate enthalpy change for the reaction, using the following combustion data C_(2)H_(4)(g) + 3O_(2)(g) rarr 2CO_(2)(g) + 2H_(2)O(g) , Delta_("comb")H^(Θ) = -1401 kJ mol^(-1) C_(2)H_(6)(g) + 7//2O_(2)(g)rarr 2CO_(2) (g) + 3H_(2)O(l) , Delta_("comb")H^(Θ) = -1550kJ H_(2)(g) + 1//2O_(2)(g) rarr H_(2)O(l) , Delta_("comb")H^(Θ) = -286.0 kJ mol^(-1)

Calculate enthalpy change (in Kj) when 2 mole of liquid acetic acid undergoes dissociation into CH_(4)(g) and CO_(2)(g) from the following date : DeltaH_(vap)[CH_(3)COOH](l)=50kJ//"mole" Resonance energy of DeltaH_(vap)[CH_(3)COOH](g)=-50kJ//"mole" Resonance energy (kJ//"mole"):C-H=400,C-O=350,o=o=500 C-C=350,O-H=450, C=O=800,H-H=400

At 27^(@)C for reaction, C_(6)H_(6)(l)+(15)/(2)O_(2)(g)to6CO_(2)(g)+3H_(2)O(l) proceeds spontaneously because the magnitude of

C_(4)H_(10)+(13)/(2)O_(2)(g)rarr4CO_(2)(g)+5H_(2)O(l), DeltaH =- 2878 kJ DeltaH is the heat of……….of butane gas.
