A lover of spectroscopy and chocolate. Re: How do I calculate enthalpy and entropy of this really complicated problem? « Reply #15 on: October 23, 2013, 02:36:30 PM » 8.31446 J/mol K. You can convert to kJ/mol K, but it's not 0.0831446; try 0.00831446. Looks like you need...
Calculate the enthalpy change for the reaction below given the standard heat of combustion for ammonia, NH3, is -226 kJ/mol. 4NH3 (g) + 5O2(g) right arrow 4NO(g) + 6H2O(g) The heat reaction is -50.0 kJ and the entropy change is -0.0025kJ/K. What is the Delta G of the reac...
How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? What is the relationship between a compound's stability and its enthalpy of formation? How to measure energy What's the difference between heat of reaction and heat of formation?
It seemed reasonable to consider both the satisfactory value of the Gibbs energy of formation determined by e.m.f. δ f G = −15940 ± 1000 J mol −1 at 100 K, and the present enthalpy of formation, in order to calculate the entropy of formation (Δ f S = 5.4 J K −1 mol...
The Clausius Clapeyron equation assumes that the substance being studied is in equilibrium between its liquid and vapor phases, and that the vapor behaves as an ideal gas. It also assumes that the change in enthalpy and entropy between the liquid and vapor phases is constant ...
To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is calculated, the mass can be found on a scale and the calculation of density can be complete...
This example problem demonstrates how to examine the reactants and products to predict the sign of the change in entropy of a reaction.
