A #7 L# container holds #7 # mol and #18 # mol of gasses A and B, respectively. Every three of molecules of gas B bind to one molecule of gas A and the reaction changes the temperature from #320^oK# to #330 ^oK#. By how much does the pressure change?
If the reaction is of the form
In the reaction 18 mol of B will bind to 6 mol of A to form 6 mol of C (assuming C is also a gas!).
1 mol of A will be left. So now we have 7 mol in stead of 25 mol.
Temperature goes from 320 K to 330 K:
More likely the reaction is of the form:
In this case the number of moles goes from:
And the fraction in step (1) will be
