Answer:
No pressure will change in the chamber at reactions end
Explanation:
CH4 + 2O2 ---> CO2 + 2H2O
According the above reaction
There are 3 moles total of gaseous reactants, and 3 moles total of gaseous products, so this reaction results in no change of volume. Therefore, since this happens at constant volume and constant temperature, the pressures are directly related to the moles used and produced. This way, no pressure will change in the chamber at reactions end
