Question Description
Hess's law of heat of summation is based on law of conservation of energy. It has found significance inderiving heats of many reactions which either do not take place or if take place, than other side reactionsalso accompany it. For example heat of reaction for C + ½ O2 → CO can not be studied directly as it occurswith simultaneous reaction of oxidation of CO to CO2. Bond energy is referred as heat enthalpy when a bondis broken to produce isolated gaseous atoms. In case of breaking up of bonds between unlike atoms e.g.,C – H bond in CH4, bond energy is referred as average bond energy as four C - H bonds are broken up.Q. If C + ½ O2 → CO(g) ; ΔH = – 110 kJ.C + H2O(g) → CO(g) + H2(g) ; ΔH = 132 kJThe mole composition of mixture of steam and O2 and steam on being passed over coke at 1273 K so that temperature remains constant is :a)0.6 : 1b)1.67 : 1c)0.3 : 1d)0.4 : 1Correct answer is option 'B'.
