Question

A gaseous reaction a2 given b + half of c who is increase in pressure from hundred to 120 metre in 5 minutes the rate of disappearance of a2 is

Answer 1

Answer:

Given the reaction is

..................................A2(g) …..............=......B(g)...... +....... 1/2C(g)

..............................100mm.......................0........................0 ….(initially)

................................100-p.....................p....................p/2....(after 5 minutes)

total pressure=(100-p)+p+p/2=120mm(given)

p/2=20

p=40mm

so rate of disappearence of A2=40mm/5min

and if we know the temperature and volume of the mixture, we can alsom calculate the amount(mole) of A2 disappeared .

Hope it's help you......
