A) 400 K
B) 873 K
C) 533 K
D) 300 K
Correct Answer: C
Solution :
\[\operatorname{Number} of moles of He = 0.3\] \[Number of moles of Ar = 0.4\] \[\operatorname{KE}\,\,of\,\,He =0.3\times R\times T\] \[\operatorname{KE}\,\,of\,\,Ar =0.4\,\,\times \,\,R\,\,\times \,\,400\] According to question, \[\operatorname{KE} \,of \,Ar \,= \,KE \,of\, Ar\] \[0.3\,\times \,R\,\times T=0.4\times R\,\times 400\] \[\operatorname{T}\,\,=\,\,\frac{0.4\times R\,\times 400}{0.3\times R}\] \[T=533\text{ }K\]You need to login to perform this action.
