The decomposition reaction of CO2(g) to produce carbon and oxygen gas consumes 462 kJ of energy. The energy levels of the produc
Semenov [28]

Answer:

higher, left

Explanation:

Given that the reaction consumes 462 kJ of energy. It means that the reaction is a endothermic reaction.

In the energy profile of the endothermic diagrams, The reactants are at a very low level as compared to the products and hence, energy is supplied to overcome this difference.

Hence, The energy levels of products are <u>higher</u> than the energy level of reactant.

Hence, already stated, heat is required by the reaction and thus heat is written to the reactant side which is to the <u>left</u> side of the equation.

In a particular experiment at 300 ∘C, [NO2] drops from 0.0100 to 0.00800 M in 100 s. The rate of appearance of O2 for this perio
Tems11 [23]

Answer:

1\times{10}^{-5}\frac{M}{s}

Explanation:

The stoichiometry for this reaction is  

2NO_2\rightarrow2NO+O_2

The rate for this reaction can be written as  

-r_{NO_2}=-\frac{d\left[NO_2\right]}{dt}=\frac{(0.01-0.008)M}{100s}=2\times{10}^{-5}\frac{M}{s}

This rate of disappearence of NO_2 can be realated to the rate of appearence of O_2 as follows  (the coefficients of each compound are defined by the stoichiometry of the reaction)

-r_{O_2}=-r_{NO_2}\times\frac{coefficient\ O_2\ }{coefficient\ NO_2}=2\times{10}^{-5}\frac{M}{s}\times\frac{1\ mole\ O_2\ }{2\ mole\ NO_2}=1\times{10}^{-5}\frac{M}{s}
