Nitrogen monoxide reacts with oxygen to give nitrogen dioxide. 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) The rate law is −Δ[NO]/Δ t = k [NO] 2 [O 2 ], where the rate constant is 1.16 × 10 −3 L 2 /(mol 2 · s) at 339 o C. A vessel contains NO and O 2 at 339 o C. The initial partial pressures of NO and O 2 arc 155 mmHg and 345 mmHg, respectively.

The rate law is −Δ[NO]/Δt = k[NO]2[O2], where the rate constant is 1.16 × 10−3 L2/(mol2 · s) at 339oC. A vessel contains NO and O2 at 339oC. The initial partial pressures of NO and O2 arc 155 mmHg and 345 mmHg, respectively. What is the rate of decrease of partial pressure of NO (in mmHg per second)?

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
