Ultracool33 Posted October 14, 2008 Share Posted October 14, 2008 Using average bond energy values estimate ΔE for the following gas phase reaction. CH2=CH2 + Br2 → BrCH2CH2Br Link to comment Share on other sites More sharing options...

ChemSiddiqui Posted October 18, 2008 Share Posted October 18, 2008 delta(small triangle) sign tells you about the difference of anything. So when its delta E it means difference in energy that occured from forward to the backward reaction. The formula is delta E = bond energy of reactants - bond energy of products. Look out the bond energy data from a chemistry data table and work out delta E urself Link to comment Share on other sites More sharing options...
