1) We apply the ideal gas equation:
PV = nRT
n = (21300 x 3/1000) / (8.314 x 323)
n = 0.024
Your answer is correct.
2) Total pressure = Partial pressure of Hydrogen + Partial pressure of water
134.7 = 122.4 + Pw
Pw = 12.3 kPa
Your answer is correct
3) The molar fraction, volume fraction and pressure fraction of gasses are the same thing.
Thus, percentage pressure of Oxygen = 10%
Pressure of Oxygen = 2.04 x 10⁴ x 0.1
= 2.04 x 10³ kPa
Your answer is correct
Well done!
Answer:
An elementary reaction is a chemical reaction in which one or more chemical species react directly to form products in a single reaction step and with a single transition state.
Answer:
Increasing the concentration of A by a factor of 3 will cause the reaction rate to (A) remain constant.
Explanation:
If the reaction order for A is zero, it means that the rate of the reaction is independent of A. The rate law would be:
r = k . [A]⁰ = k
where,
r is the rate of the reaction
k is the rate constant
and [A] is raised to its reaction order (zero)
Increasing the concentration of A by 3 would result in no effect on the reaction rate, as we can see in the rate law:
r = k . [3 A]⁰ = k .1 = k
Answer:
D.ionic interaction is a strong interaction
