Answer :
(a) The average rate will be:
(b) The average rate will be:
Explanation :
The general rate of reaction is,
Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.
The expression for rate of reaction will be :
From this we conclude that,
In the rate of reaction, A and B are the reactants and C and D are the products.
a, b, c and d are the stoichiometric coefficient of A, B, C and D respectively.
The negative sign along with the reactant terms is used simply to show that the concentration of the reactant is decreasing and positive sign along with the product terms is used simply to show that the concentration of the product is increasing.
The given rate of reaction is,
The expression for rate of reaction :
Thus, the rate of reaction will be:
<u>Part (a) :</u>
<u>Given:</u>
As,
and,
<u>Part (b) :</u>
<u>Given:</u>
As,
and,
Your answer is mass and speed! Please give me brainlist :)
The balanced chemical equation is :
LiBr (aq) + H2O (l) → LiOH (aq) + HBr (aq) .
<h3>Explain the balanced chemical equation?</h3>
- To balance a chemical equation, add coefficients to the symbols or formulas as needed so that the same number of each type of atom occurs in both reactants and products.
- There is a strategy that can help you balance equations faster. It is known as balancing by inspection. Essentially, you take the number of atoms on each side of the equation and add coefficients to the molecules to balance out the number of atoms.
- Lithium bromide, abbreviated LiBr, is a chemical compound. It is water, alcohol, and ether soluble. It is made by reacting hydrobromic acid with lithium hydroxide.
