Through the process of synthesis, 2 pharmaceutical products are obtained, sample 1 and sample 2. After this, they are separated using High Performance Liquid Chromatography (HPLC). Stationary phase volume in column = 3.10 mL
Volume of mobile phase in column = 8.60 mL
Partition coefficients products on the column for sample 1 = 19.0
Partition coefficients products on the column for sample 2 = 21.0
Unretained peak time = 1.50 min

Required: Find the number of theoretical plates required to obtain a baseline separation for the two peaks from the samples.

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
