Question

In how many times should we increase the pressure in order to increase the rate of the one-stage reaction 2А(g) + В(g) → А2В(s) in 8 times

Answer 1

Answer:

A

2

(g)→B(g)+

2

1

C(g)

100 0 0 ---------------- initial

100-P P P/2 ---------------- after 5 min

After 5 minutes

Total pressure ⇒(100−P)+P+

2

P

=120mm

2

P

=20

P=40mm

So, rate of disappearance of A

2

=

5min

40mm

=8mm/minute
