Physical Chemistry Barometric Derivation!!! 1. The problem statement, all variables and given/known data Derive an expression for the barometric equation that takes the temperature dependency (To=T-az) into account. Where To=ground level temperature, T=temperature at an altitude, a=proportion constant, z=altitdue 2. Relevant equations p=poe-gMz/RT 3. The attempt at a solution I know how to derive the barometric equation formula to get to ln(p/po) which i know has to be part of the final expression. however, I having trouble with the integral on the other side. should i integrate for dz or dT?
