A 5 L container holds 12 mol and 9 mol of gasses A and B, respectively. Every three of molecules of gas B bind to four molecule of gas A and the reaction changes the temperature from 360^oK to 420 ^oK. By how much does the pressure change?

the pressure change from 126 Bar to 12 Bar
Explanation:
the reaction is
so if at the beginning you have (12+9) = 21 mol of gases, after the reaction you have 3 mol of gas( we don't know if we have still gas?)
at the beginning with the gases'law, we have:
after the reaction:
