Concept explainers
Interpretation:
The special stability of chelates has to be explained with an example.
Concept Introduction:
Entropy means “randomness or disorderliness”. Entropy is a
The term free energy refers to available energy in the system to do work. Lesser the energy of the system more will be the stability of the system. It is denoted by ‘G’ and change in free energy is represented as
Enthalpy of the system refers to heat content of the system and it is denoted by ‘H’. Change in enthalpy is denoted as
These three thermodynamic terms are related as,

- The following data were collected for the reaction, H2(g) + L(g) ** - HI(g), at equilibrium at 25°C: [HJ = 0.10 mol L-1, [IJ = 0.20 mol L"\ [HI] = 4.0 mol L’1 Calculate the equilibrium constant for the reaction at this temperature.arrow_forwardComparing the chemistry of carbon and silicon. (a) Write balanced chemical equations for the reactions of H2O() with CH4 (forming CO2 and H2) and SiH4 (forming SiO2 and H2). (b) Using thermodynamic data, calculate the standard free energy change for the reactions in (a). Is either reaction product-favored at equilibrium? (c) Look up the electronegativities of carbon, silicon, and hydrogen. What conclusion can you draw concerning the polarity of CH and SiH bonds? (d) Carbon and silicon compounds with the formulas (CH3)2CO (acetone) and [(CH3)2SiO]n (a silicone polymer) also have quite different structures. Draw Lewis structures for these species. This difference, along with the difference between structures of CO2 and SiO2, suggests a general observation about silicon compounds. Based on that observation, do you expect that a silicon compound with a structure similar to ethene (C2H4) exists?arrow_forwardThe space shuttle Orbiter utilizes the oxidation of methylhydrazine by dinitrogen tetroxide for propulsion: 4N2H3CH3(l)+5N2O4(l)12H2O(g)+9N2(g)+4CO2(g) Calculate H for this reactionarrow_forward
