I know the equation is: ΔH(reaction)= ΔE(reaction) +RTΔn(gases) but that's as far as i've been able to get. Thanks for the help Logged Enthalpy Chemist Sr. Member Posts: 4036 Mole Snacks: +304/-59 Re: Calculate deltaE of reactions?
Delta G Equation at Standard State Change in G at Equilibrium Lesson Summary Frequently Asked Questions What does Delta G mean? Delta G is the difference in Gibbs free energy between the products and reactants of a reaction. If Delta G is positive, the reaction is non-spontaneous, if...
How to write the equation for the combustion of ethane C_2H_6? The combustion of ethane in the presence of excess oxygen yields carbon dioxide and water: *2C_2H_6 (g) + 7O_2 (g) --> 4CO_2 (g) + 6H_2O What is the value of Delta G� for this reaction?
- T = temperature From this equation, we can infer that ΔH<ΔU when ΔNg is negative. This is because if ΔNg is negative, it will subtract from ΔU, making ΔH less than ΔU. 1. Analyze the Reactions: We will analyze each reaction to determine ΔNg....
ATime dependent problem with a delta function Hello, I try to solve a time dependent problem described by a Hamiltonian of the type $$ \mathcal{H}(t) = H_0 + V \delta(t) .$$ I started by trying to solve the Schrödinger equation with ##H_0 = p^2 / 2m##, but I'm gettin...

where δij is the Kronecker-delta symbol of Cartesian-tensor notation. The extra source/sink term in the k equation, due to the “direct interaction” of the particles with the surrounding fluid, is given by the work done by the particles on the surrounding fluid: (7)ɛp=<uifi>p wher...
The results of final cytotoxicity assays using a narrow range of compound concentrations are shown in Figure 1. The assays were conducted to identify the subtoxic concentrations in order to avoid toxic effects in the cellular model used. Cell viability was determined after 24 h of treatment with...
Use Hess' Law to calculate enthalpy of reaction for the following equation: 2N2(g) + 5O2(g) rightarrow 2 N2O5(g) Given: 2 H2(g) + O2(g) rightarrow 2 H2O(l) Delta H = -571.6 kJ/mol N2O5(g) + H2O(l) rightarrow 2 HNO3(l) Delta H = -76.6 kJ/mol 1/...
The change in free energy for a given process at a particular temperature depends on three factors, as seen from the equation ΔG = ΔH − TΔS, where ΔH is the change in the enthalpy of the system, T is the temperature in degrees Kelvin, and ΔS is the change in entropy. A ...
