a$)$ Calculate the diffusion coefficient of $H2$ in a mixture containing $8\%$molH$2,42\%$molO$2,10\%$molCO and $40\%$molCl$2$ at the pressure of $2$atm and $t=60C.$

$v_{H_2}=14\mathrm{.}3\frac{c{m}^3}{(mol)}$

$v_{O_2}=25\mathrm{.}6\frac{c{m}^3}{mo{l}^3}$

$v_{CO}=30\mathrm{.}7\frac{c{m}^3}{mo{l}^3}$

$v_{C{l}_2}=48\mathrm{.}4\frac{c{m}^3}{(mol)}$

b$)$ Calculate the diffusion coefficient of $CO$ in ethyl alcohol at $t=30C.$

${}_{30}=1\mathrm{.}1cP$

$=1\mathrm{.}5$

$V_b=30\mathrm{.}7\frac{c{m}^3}{(mol)}$
