sir ...........consider the reaction A->B+C

                      A(g)      ->         B(g)+C(g)

AT TIME T=0 p1 atm  ->         0atm   0atm

AT TIME T     (P1-x)atm          xatm   xatm

where x is the decrease in partial pressure of A and increase in partial pressure of B&C.

my question is---why is  there a decrease in partial pressure in A and why is there a increase in partial pressure of B and C.it is very confusing...............thank you

Expert Answer:

Dear Kaamilahamed

In the reaction of A --> B + C
When reaction proceeds, the amount of A gas decreases. So, the partial pressure of A keeps on decreasing.
As reaction proceeds, the amount of B and C increases, hence the partial pressure of B and C increases.
