Stereochemistry and Isomerism

Stereochemistry deals with the three-dimensional structure and properties of molecules. It explains the arrangement of atoms and their manipulation within a molecule in a 3D structure. Stereochemistry can be dealt with all types of molecules. Based on the stereochemistry of a molecule, the physical and chemical properties of the molecules vary.

Nitroglycerine is a shock-sensitive compound that decomposes as follows: 2 C3H5N3O9(l) --> 6 CO2(g) + 3 N2(g) + ½ O2(g) + 5 H2O(g) 10.0 kg of nitroglycerine sits in a 5.0-L cylinder. A chemist, angry that an experiment didn’t work, foolishly kicks the cylinder, thereby inadvertently performing his last and most dramatic experiment. The final temperature of the product mixture is 595 oC. Assume ideal gas behavior and complete decomposition. Calculate the total pressure (atm) in the cylinder the moment before the explosion.
