The bond energy of an O- H bond is 109 kcal mol 1. When a mole of water is formed from H and O atoms, then 218 kcal is released. Two O-H bonds are there is H2O so 2*109 kcal an
Drying - Chemical Properties of oils and fats Some fixed type of oils, containing glycerides of unsaturated fatty acids comprising two or three double bonds have the trend of s
What are the Advantages of cold working (i) No heat is required. (ii) Better surface finish is obtained. (iii) Superior dimension control. (iv) Improved strength and h
The reaction A ? B + C is known to be zero order in A and to have a rate constant of 5.0 x 10-2 mol/L·s at 25 oC. An experiment was run at 25 oC where [A]0 = 1.0 x 10-3 M. a)
No, it does not depend upon concentrations of reactants, From the Arrhenius equation, k = Ae^(-Ea/RT) We can say, that it is dependent on activation energy(Ea) and temperatu
