Question

The increasing order of effusion among the gases, H2, O2, NH3, and CO2, is
a) H2, CO2, NH3, O2
b) H2, NH3,O2, CO2,
c) H2, O2, NH3, CO2,
d) CO2,O2, NH3, H2,
​

Answer 1

Answer:

option (d)

Explanation:

molecular weight is inversely proportional to rate of effusion CO2=44

O2=32

NH3=17

H2=2

Answer 2

Rate of effusion of gases is inversely proportional to square root of molecular mass of gases.

Rate∝

M

1

. The smaller the value of M, more is the rate of effusion

so d) co2,o2,nh3,h2 is correct answer
