Speeds up the reaction but does not change k

notka56 [123]

The answer is catalyst.

A catalyst is characterized by acceleration the rate of a chemical reaction but not modifiy the equilibrium, which is what k represents (the constant of equilibrium of the reaction).

The catalyst manages that the reaction goes through a different pathway, with a lower activation energy, so the transition compound is reached faster and the whole reaction goes faster, but the final species and their equilibriium concentrations do not change.

determine the total pressure of gas mixture the contains oxygen, nitrogen, and helium if the partial pressures of the gases are

timurjin [86]

0.922 atm is the total pressure of gas mixture that contains oxygen, nitrogen and helium gases.

Explanation:

Data given:

partial pressure of the oxygen p $O_{2}$ = 0.197 atm

partial pressure of the nitrogen gas p $N_{2}$ = 0.461 atm

partial pressure of the helium gas pHe = 0.264

total pressure P in the gas mixture= ?

We know that individual gases exert pressure on the mixture of gases independently. From Dalton's law of pressure it is said that sum of partial pressure of all the gases in the mixture equals its total pressure. So,

Ptotal = p $O_{2}$ + p $N_{2}$ + pHe

putting the values in the mixture:

Ptotal = 0.197 + 0.461+ 0.264

Ptotal = 0.922 atm

Total pressure is 0.922 atm.

Express in scientific notation. Make sure your answer has the same number of significant figures as the starting value. (6.0 x 1

Greeley [361]

I believe the correct answer from the choices listed above is the second option. The expression (6.0 x 104) (3.1 x 10-1) is equal to 1.9 x 10^4. We only have two significant figures from the starting expression that is why we rounded of the product from 1.86 to 1.9.
