Answer:
The answer to your question is 25.9 g of KCl
Explanation:
Data
Grams of KCl = ?
Volume = 0.75 l
Molarity = 1 M
Formula
Solve for number of moles
Substitution
Number of moles = 1 x 0.75
Simplification
Number of moles = 0.75 moles
Molecular mass KCl = 39 + 35.5 = 34.5
Use proportions to find the grams of KCl
34.5 g of KCl ---------------- 1 mol
x ---------------- 0.75 moles
x = (0.75 x 34.5) / 1
x = 25.9 g of KCl
Answer:
The reactions free energy
Explanation:
From the question we are told that
The pressure of (NO) is
The pressure of (Cl) gas is
The pressure of nitrosly chloride (NOCl) is
The reaction is
⇆
From the reaction we can mathematically evaluate the (Standard state free energy ) as
The Standard state free energy for NO is constant with a value
The Standard state free energy for is constant with a value
The Standard state free energy for is constant with a value
Now substituting this into the equation
The pressure constant is evaluated as
Substituting values
The free energy for this reaction is evaluated as
Where R is gas constant with a value of
T is temperature in K with a given value of
Substituting value
