Number of moles : n₂ = 1.775 moles
<h3>Further explanation</h3>Given
Moles = n₁ = 1.4
Volume = V₁=22.4 L
V₂=28.4 L
Required
Moles-n₂
Solution
Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
The ratio of gas volume will be equal to the ratio of gas moles
Input the values :
n₂ = (V₂ x n₁)/V₁
n₂ = (28.4 x 1.4)/22.4
n₂ = 1.775 moles
Answer:
- False.
- False.
- True.
- True.
Explanation:
Hello, for each statement we state:
- An exponent of "2" means that if we double the concentration of the reactant the rate doubles as well.
FALSE because considering a rate law like:
The exponent of "2" powers the concentration to the second power, not doubles the rate law, thus, if C is 3, for k=1, r will be -9. On the other hand if the rate is like:
The rate will be -3, that is why the rate is not doubled when the "2" in concentration is present.
- Exponents in rate laws are based on the coefficients from the balanced equation.
FALSE because for nonelemental chemical reactions, the exponents do not match with each species' stoichiometric coefficients in the rate law.
- The rate constant, k, takes into account the effect of activation energy and temperature on the reaction.
TRUE, since the Arrhenius equation allows us to prove the effect of the activation energy and the temperature:
- Differential rate laws allow us to compare concentration and time.
TRUE as they are given like:
