How do the rates of the forward and reverse reactions change throughout a reaction?
fenix001 [56]
The rates of the forward and reverse reaction depends on the temperature on which the reaction will proceed, either endothermic of exothermic. it also depends of the concentration of the reactants and products. if the reaction is exothermic, so if the reaction temperature is increased then it will favor the forward reaction, then if the reaction is lowered then it will favor the reverse reaction

Perform each of the following unit conversions using the conversion factors given below:
andrezito [222]

1. 1086.04 mmHg

2.70.213 mmHg

3. 95.954 kPa

<h3>Further explanation</h3>

Pressure (P) is the force applied per unit area

Can be formulated :

\tt P=\dfrac{F}{A}

P = pressure (SI=Pascal(Pa))

F= force applied (N)

A=area(m²)

The unit of pressure can be expressed in atm, mmHg, or Pascal

\tt 1.\dfrac{1.429}{1}\times 760=1086.04~mmHg

\tt 2)~9,361~Pa=9.361~kPa=\dfrac{9.361}{101.325}\times 760=70.213~mmHg

\tt 3)\dfrac{725}{760}\times 1=0.947~atm=\dfrac{0.947}{1}\times 101.325=95.954~kPa

The atmosphere of the planet Mars is 95.3% carbon dioxide, 2.6% nitrogen, 1.9% argon, with the remaining fraction being traces o
kodGreya [7K]

Answer:

Mean Partial pressure of Nitrogen in Mars' atmosphere = 15.86 Pa

Explanation:

According to Dalton's law of Partial Pressure, the total pressure exerted by a mixture of ideal gases (that do not react together) is the sum of the partial pressures of the individual gases that make up the mixture. It goes further to explain that the partial pressure of a gas in a mixture of gases is equal to its mole fraction of that gas multipled by the total pressure exerted by the mixture of gases.

Total Pressure exerted by the mixture of gases in the atmosphere on Mars = Mean atmospheric pressure on Mars = 610 Pa

Partial pressure of Nitrogen = (mole fraction or mole percentage of Nitrogen in the atmosphere) × (total pressure exerted by all the gases in the atmosphere)

Mole percentage of Nitrogen in the atmosphere of Mars = 2.6%

Partial pressure of Nitrogen = 2.6% × 610 = 15.86 Pa

Mean Partial pressure of Nitrogen in Mars' atmosphere = 15.86 Pa

Hope this Helps!!!
