# How exactly can an increase temperature be used to break the chemical bonds of a gas [SO2, for example]?

So I understand the ideal gas law at a basic level, and that a rise in temperature can break bonds, however, I am unclear of how this works in a practical sense.

Say I have a container full of $\ce{SO2(g)}$ and I would like to break $\ce{SO2}$ into Sulfur ($\ce{S}$) and molecular oxygen ($\ce{O2}$). Would simply increasing the heat of the container to $n~\pu{K}$ be sufficient to break the bonds to get $\ce{S}$ and $\ce{O2}$ by themselves?

• Imagine the molecules in motion. As temperature increases, the motion becomes more violent. What do you think happens when the collisions between molecules or vibrations within a molecule increase? Jan 4, 2018 at 15:47
• Right, they break apart. I think I got it, thanks! Jan 4, 2018 at 18:04
