Question
Answer in Python. Given this code to start with (definitions for the Saha and Boltzmann Equations), I must: use the Saha equation (defined in the second code block) to find the temperature of the partial ionization zone for a certain gas.
(Hint: The Saha function will return answers for the Saha equation for gases of arbitrary composition)
