Answer:
Frequency = 22
Relative frequency = 44%
Explanation:
Hello,
To find the frequency of the blood group o, we've just got to count the amount of blood group o donors, thus, the result is 22. On the other hand, if you're required to find the relative frequency, you divide the aforesaid result by the total amount of donors as shown below:
%
%
Best regards.
The balanced chemical equation is :
Moles of ,
Now, by given chemical equation , we can see 2 mole of react with 1 mole of
.
So , 2.27 mole react with :
Mass of oxygen is :
Therefore, mass of oxygen in grams produced is 18.16 g.
Hence, this is the required solution.
Answer : The value of equilibrium constant for this reaction at 328.0 K is
Explanation :
As we know that,
where,
= standard Gibbs free energy = ?
= standard enthalpy = 151.2 kJ = 151200 J
= standard entropy = 169.4 J/K
T = temperature of reaction = 328.0 K
Now put all the given values in the above formula, we get:
The relation between the equilibrium constant and standard Gibbs free energy is:
where,
= standard Gibbs free energy = 95636.8 J
R = gas constant = 8.314 J/K.mol
T = temperature = 328.0 K
K = equilibrium constant = ?
Now put all the given values in the above formula, we get:
Therefore, the value of equilibrium constant for this reaction at 328.0 K is
