Airida [17]2 years ago
6 0

Answer:

Carbon Dioxide (CO2) is a chemical compound consisting of one carbon atom and two oxygen atoms. ... Carbon Monoxide (CO) is a chemical compound which contains one carbon atom and one oxygen atom and is also a colourless and odourless gas. Unlike CO2, it is entirely human-made and is not naturally present in the atmosphere.

N76 [4]
To solve this problem, you need to recognize that the ratios of the coefficients must be equal. So the ratio for this system would be k/4 = -3/-5. Solving for k we get k = (3)*(4)/5 = 12/5, hence the answer is A. Hope that helps!

When the chemical reaction 2no(g)+o2(g)→2no2(g) is carried out under certain conditions, the rate of disappearance of no(g) is 5
viktelen [127]

The rate of disappearance of O2(g) under the same conditions is 2.5 × 10⁻⁵ m s⁻¹.

<h3>What is the rate law of a chemical equation? </h3>

The rate law of a chemical reaction equation is usually dependent on the concentration of the reactant species in the equation.

The chemical reaction given is;

\mathbf{2 NO_{(g)} + O_{2(g)} \to 2 NO_{2(g)} }

The rate law for this reaction can be expressed as:

\mathbf{= -\dfrac{1}{2}\dfrac{d[NO]}{dt} = -\dfrac{1}{1}\dfrac{d[O_2]}{dt}= +\dfrac{1}{2}\dfrac{d[NO_2]}{dt}}

Recall that:

  • The rate of disappearance of NO(g) = 5.0× 10⁻⁵ m s⁻¹.

  • Since both NO and O2 are the reacting species;

Then:

  • The rate of  disappearance of NO(g) is equal to the rate of  disappearance of O2(g)

\mathbf{= -\dfrac{1}{2}\dfrac{d[NO]}{dt} = -\dfrac{1}{1}\dfrac{d[O_2]}{dt}}

\mathbf{= -\dfrac{1}{2} \times 5.0 \times 10^{-5}  = rate \  of  \ disappearance \ of  \ O_2}

Thus;

The rate of disappearance of O2 = 2.5 × 10⁻⁵ m s⁻¹.

Therefore, we can conclude that two molecules of NO are consumed per one molecule of O2.
