The ratio of the RMS speeds of CH4 at T1 and SO2 at 300 K is 4:1. The average kinetic energy per mole of CH4 is
Options:
Answer:
A
Solution:
(urms)/(CH4)urms(SO2) = √((T1/16)/)300/64 = 4 ⇒ (T1 × 64)/(16 × 300) = 16 ⇒ (T1)/75 = 16 ⇒ T1 = 1200 K. KE per mole = 3/2RT1 = 3/2(2)(1200) = 3600 cal (using R = 2 cal mol-1 K-1). Confirms Ans (a) 3600 cal.
