hey student
for this question please keep in mind the basic defination of gay lusacs law and also take reference to the balanced chemical equation.
write down the balanced chemical equations for both the process and take the help from this statement
This relationship between temperature and pressure is known as Gay-Lussac's law. It states that if the volume of a container is held constant as the temperature of a gas increases, the pressure inside the container will also increase. As with the other gas laws, this one can be represented in the form of an equation:

P1/T1 = P2/T2

Recall that we use 1s and 2s to indicate the quantities before (1s) and after (2s) a change has taken place. Also, note that the units for pressure do not matter, as long as they are the same throughout the entire equation. The units for temperature must be Kelvins or the equation will not work. This is because the Kelvin scale is an absolute scale - it doesn't go negative. Finally, this equation only works for an ideal gas. Most gases that surround you and me behave very much like ideal gases, so we can use this equation as an approximation for the gases we encounter.
