steps. The uvelan U number of enzyme-catalyzed is C6H1206 (s) → 2C2H3OH(I) + 2CO2(g) Calculate the standard enthalpy change for this reac- tion, assuming that the carbohydrate is a-D-glucose. Bond Enthalpy 3.58 (a) Explain why the bond enthalpy of a molecule is always defined in terms of a gas-phase reaction. (b) The bond dissociation enthalpy of F2 is 150.6 kJ mol-1. Calculate the value of ArHo for F(g) 3.59 From the molar enthalpy of vaporization of water at 373 K and the bond dissociation enthalpies of H2 and O2 (see Table 3.4), calculate the average O-H bond enthalpy in water, given that H2(0) +02(9) H2Ou) 285.8 kJ mol-1 3.60 Use the bond enthalpy values in Table 3.4 to cal- culate the enthalpy of combustion for ethane, 2C2H6(g) + 702 (g) → 4CO2(g) + 6H20(1) Compare your result with that calculated from the nthalpy of formation values of the products and reac- ants listed in Appendix 2.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
