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.

Fittoniya [83]

It can be deduced that the model that  match the recall details will be if(modelYear <=2006 && modelYear >= 2001) {cout << "RECALL" ;}.

<h3>What is a model?</h3>

A computer model simply means an abstract mathematical representation of real-world events, systems, behavior, etc.

A computer model is designed to behave just like the real-life system. In this case, Clunker motors inc. is recalling all vehicles in its extravagant line from the model years. This is depicted above.

You get a C on your psychology exam. Given this scenario, describe and give an example of an upward comparison, a downward compa
Elza [17]

Answer:

For this given question, when a student have a Grade C, his first thinking is, if his peers also got the same grade.

He derives a satisfaction (self serving bias) by thinking that in this situation, many are in his shoes too. when he thinks about those that performed better and in an upper/higher level he feels they are always up there no matter the situation, and he tries to console himself.

For those in the lower level or downward comparison, he thinks he is better than them, so this thoughts of him motivates him, thereby having a sense of superiority over others.

Explanation:

When a student gets a grade C, the first thing in his mind are those who also got the same grade as him.

He wants to get a satisfaction by thinking that many are in same level as he is. When he thinks of those in the upper or higher level he notice that those who are in the upper level are always in the higher position. But he always tries to make the whole scenario to favor of him. he thinks that those who are in A and B grade should always perform better. But in regards to their position he does not think so.

Naturally there was no situation favorable in improve the grade.

Also,when he thinks of the lower level he thinks that he is in better position since many are in down in position. this encourages him and a sense of superiority over others works in this case.
