Question

CO₂ is a triatomic gas. Mean kinetic energy of one gram gas will be (If N – vogadro's number, K - Boltz mann's constant and molecular wieght of CO₂ = 44) :-

(a) (3/8)NKT

(b) (5/88)NKT

(c) (6/88)NKT

(d) (7/88)NKT

Answer 1

Correct Option (d) (7/88)NKT

Explanation: 

Mean kinetic energy for n moles of gas =nxf/2RT

=7/88NKT   [AS f = 7 for co₂]
