At definite temperature, the tootal pressure of a gas mixture consisting of three gases A,B and C are 2,4,and 6 , then the increasingorder of their partial pressure is ___ 

Option: 1

\mathrm{P_A=P_B=P_C}


Option: 2

\mathrm{P_A>P_B>P_C}


Option: 3

\mathrm{ P_A<P_B<P_C}


Option: 4

\mathrm{P_A \neq P_B \neq P_G}

The mole fractions of A,B,and C in the mixture,

                                \mathrm{\begin{aligned} & x_A=\frac{2}{12}=\frac{1}{6} \\ & x_B=\frac{4}{12}=\frac{1}{3} \\ & x_C=\frac{6}{12}=\frac{1}{2} \end{aligned}}

Therefore, the partial pressure of gas A, 

                                            \mathrm{\begin{aligned} & P_A=\frac{P}{6} \\ & P_B=\frac{P}{3} \\ & P_c=\frac{P}{2} \end{aligned}}

\mathrm{\therefore P_A<P_B<C}
