determine the entropy change for the displacement reaction represented by the following equation :
Cl2 + PbBr2 -> PbCl2 + Br2
Cl2 = 223.066 delta S
PbBr2 = 182.7 delta S
PbCl2 = 131.3 delta S
Br2 = 152.231 delta S
To determine the entropy change for the displacement reaction, you need to calculate the difference between the total entropy of the products and the total entropy of the reactants. Here's how you can do it:
1. Start by adding up the entropy values of the products:
Entropy of PbCl2 = 131.3 delta S
Entropy of Br2 = 152.231 delta S
Total entropy of products = Entropy of PbCl2 + Entropy of Br2
2. Next, add up the entropy values of the reactants:
Entropy of Cl2 = 223.066 delta S
Entropy of PbBr2 = 182.7 delta S
Total entropy of reactants = Entropy of Cl2 + Entropy of PbBr2
3. Finally, calculate the entropy change (delta S) by subtracting the total entropy of the reactants from the total entropy of the products:
delta S = Total entropy of products - Total entropy of reactants
Substitute the values calculated in steps 1 and 2 into the equation to find the entropy change for the reaction.
