The earth's atmosphere is known to be a layer of gases that are surrounded by the earth and retained by the earth's gravity. The gases in the earth actually contain roughly 78% nitrogen, 21% oxygen, 0.97% argon and carbon dioxide, 0.04% trace amounts of other gases, and water vapor. This combination of gases is commonly called air.

A 0.245-L flask contains 0.467 mol co2 at 159 °c. Caculate the pressure using Van der Walls equation
AlladinOne [14]

Answer:

The right answer is "60.56 atm".

Explanation:

As we know,

Vander wall's equation is:

⇒ (P+\frac{n^2 a}{v^2} )(v-nb)=nRT

or,

⇒ P=\frac{nRT}{(v-nb)}-\frac{n^2 a}{v^2}

Here,

a = 3.59 L² atm mol⁻²

b = 0.0427 L mol⁻¹

By putting the values in the above equation, we get

⇒ P=\frac{0.467\times 0.0821\times 432}{0.245-0.467\times 0.0427}

       =\frac{(0.467)^2\times 3.49}{(0.245)^2}

       =73.61-13.05

       =60.56 \ atm

  • Catalysts reduces the activation energy and makes reaction proceed very fast. They generally increase the rate of chemical reactions.
  • Catalysts like temperature affects the rate of chemical reaction. Chemical reactions increases as temperature increases.
  • Catalysts in the human body are very useful because they help chemical reactions in the body to proceed at a much faster rate.
