Calculate the ratio of the effusion of ( CO ) and ( N ₂ ), when temperature and pressure gradients are held constant?
Options
- A(1: 2 )
- B(1: 1 )
- C(2: 1 )
- D(1: 4 )
Correct answer
B. (1: 1 )
Step-by-step solution
The rate of effusion of a gas is inversely proportional to the square root of the mass of its particles. Rate of effusion ( 1 Molecular mass ) If two gases ( CO ) and ( N ₂ ) are at the same temperature and pressure, the ratio of their effusion rates is inversely proportional to the ratio of the square roots of their molar masses. ( Rate effusion of CO Rate of effusion of N ₂ M_ N ₂ M_ CO ) ( 28 28 1: 1 ) Hence, the correct option is (b).
