assume the products of combustion are carbon dioxide gas and liquid water. write a balanced chemical equation. what is the heat of formation of Quinine?

Assume the products of combustion are carbon dioxide gas and liquid water. Write a balanced chemical equation. What is the heat of formation of quinine?

Answer 1

quenine C6H2O, sval y GM402 + 68024 6 CO2 + 2H30 Ce) here, product of combustion reaction – H0 and and this is the balanced chemical pont of combustion of Colla

Now, Formation reaction of 130 & co, :- | H2 (1) + (3) + H,0(%) AH (99) -285 andC(9) + , 9) 760292.44; (0) I Now Adding and and substracting & from I them we get be 2H2 +0,+62 + 602- GHq 02 - 602 -> 2H,0 + 6002–6602-2730 1 7212 + O₂ + 66 Cathoz formation A reaction of So, for this reaction, change H402 in enthalpy (1H) = 6(AH/° (602) + 2 (947° (420) - AH com (quinine) = 6*(-393.5) + 2 (-285-8) - (-2750) kJ/mol =-182.6 kJ/mol Ale= heat of formation Alle = heat of combustion
here I have take the heat of formation values of water and Carbon dioxide from some source (as it is not given).

Thanks
