Draw a labelled diagram for the following: 1)Energy profile diagram for an exothermic reaction

2) Blotzmann distribution curve

Ineed ! i have no clue how to do this problem.

What is the oxidation state of each individual carbon atom in c2o42−?

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).
