Question: Consider the equilibrium C2H6 (g) ⇌ C2H4 (g) + H2 (g). At 1000 K and a constant total pressure of 1 bar, C2H6 (g) is introduced into a reaction vessel. The total pressure is held constant at 1 bar and at equilibrium the composition of the mixture in mole percent is as follows: H2 (g), 26%; C2H4 (g), 26%; and C2H6 (g), 48%.

Question: Use average bond enthalpies (linked above) to calculate the enthalpy change for the following gas-phase reaction. C2H4(g) + Br2(g) ---> CH2BrCH2Br(g) a.) To analyze the reaction, first draw Lewis structures for all reactant and product molecules. b.) ΔHreaction = kJ

Problems: 13. Given the following reaction: C2H4( g)+HBr(g)→C2H5Br(g) a. Write a Q expression for this reaction b. Calculate Q when PC2H4=1.57 atm,PHBr=2.01 atm, and PC2H5Br=0.83 atm c. If ΔG∘rxn=−76.9 kJ/mol, calculate ΔG at the above pressure, assume the reaction is occurring at 25∘C d. How does ΔG compare to ΔG∘ ? e.

Balance the combustion reaction in order to answer the question. Use lowest whole‑number coefficients. combustion reaction: C2H4+O2 CO2+H2O A conbustion reaction occurs between 3.5 mol O2 and 185 g C2H4. Upon completion of the reaction, is there any C2H4 remaining? Yes, there is still C2H4 remaining. No, all of the C2H4 is used up in the ...

The heat of reaction for the decomposition of ethane gas into ethylene gas and hydrogen gas is 136.94 kJ per mole of C2H4 formed, so it is endothermic. The reaction is run at high temperature, in part because at 800-900 °C, the equilibrium constant for the reaction is much higher, indicating that a higher percentage of products forms at this ...
