Δ H ° rxn for the given reaction is to be determined. Concept introduction: The heat of the reaction ( Δ H rxn ° ) is defined as the heat released or absorbed during a chemical reaction as a result of the difference in the bond energies (BE) of reactant and product in the reaction. Δ H rxn ° is negative for exothermic reaction and Δ H rxn ° is positive for an endothermic reaction. The formula to calculate Δ H rxn ° of reaction is as follows: Δ H rxn ° = ∑ BE reactant bond broken − ∑ BE product bond formed

Interpretation Introduction

Interpretation:

ΔH°rxn for the given reaction is to be determined.

Concept introduction:

The heat of the reaction (ΔHrxn°) is defined as the heat released or absorbed during a chemical reaction as a result of the difference in the bond energies (BE) of reactant and product in the reaction. ΔHrxn° is negative for exothermic reaction and ΔHrxn° is positive for an endothermic reaction.

The formula to calculate ΔHrxn° of reaction is as follows:

ΔHrxn°=∑BEreactant bond broken−∑BEproduct bond formed

d. In Figure 4, each stationary phase shows some negative correlation between plate count and retention factor. In other words, as k' increases, N decreases. Explain this relationship between k' and N. Plate Count (N) 4000 3500 2500 2000 1500 1000 Figure 4. Column efficiency (N) vs retention factor (k') for 22 nonionizable solutes on FMS (red), PGC (black), and COZ (green). 3000 Eluent compositions (acetonitrile/water, A/W) were adjusted to obtain k' less than 15, which was achieved for most solutes as follows: FMS (30/70 A/W), PGC (60/40), COZ (80/20). Slightly different compositions were used for the most highly retained solutes. All columns were 50 mm × 4.6 mm id and packed with 5 um particles, except for COZ, which was packed with 3 um particles.
