Answer:
Explanation:
You don't give the reaction, but we can get by just by balancing atoms of Na.
We know we will need the partially balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.
M_r: 142.04
2NaOH + … ⟶ Na₂SO₄ + …
n/mol: 0.75
1. Use the molar ratio of Na₂SO₄ to NaOH to calculate the moles of NaF.
Moles of Na₂SO₄ = 0.75 mol NaOH × (1 mol Na₂SO₄/2 mol NaOH
= 0.375 mol Na₂SO₄
2. Use the molar mass of Na₂SO₄ to calculate the mass of Na₂SO₄.
Mass of Na₂SO₄ = 0.375 mol Na₂SO₄ × (142.04 g Na₂SO₄/1 mol Na₂SO₄) = 53 g Na₂SO₄
The reaction produces of Na₂SO₄.
Complete Question
The rate of a certain reaction is given by the following rate law:
rate Use this information to answer the questions below.
What is the reaction order in ?
What is the reaction order in ?
What is overall reaction order?
At a certain concentration of H2 and I2, the initial rate of reaction is 2.0 x 104 M / s. What would the initial rate of the reaction be if the concentration of H2 were doubled? Round your answer to significant digits. The rate of the reaction is measured to be 52.0 M / s when [H2] = 1.8 M and [I2] = 0.82 M. Calculate the value of the rate constant. Round your answer to significant digits.
Answer:
The reaction order in is n = 1
The reaction order in is m = 1
The overall reaction order z = 2
When the hydrogen is double the the initial rate is
The rate constant is
Explanation:
From the question we are told that
The rate law is
The rate of reaction is
Let the reaction order for be n and for
be m
From the given rate law the concentration of is raised to the power of 1 and this is same with
so their reaction order is n=m=1
The overall reaction order is
At
= >
given that the concentration of hydrogen is doubled we have that
=>
So equating the two k
=>
So when
We have
