Answer:
A
Explanation:
The forward reaction would be favoured as the increase in temperature would cause more heat for the reaction to absorb so the endothermic reaction would be increased.
Answer:
There is 114.53 grams of acetic acid in 1.30 qt of sample
Explanation:
Step 1: Data given
Volume of vinegar = 3.60 mL
Volume of 0.130 M NaOH = 43.0 mL
1 qt = 0.946353 L
1.30 qt = 1.23026 L = 1230 mL
Step 2: Calculate moles of NaOH
Moles NaOH = molarity * volume
Moles NaOH = 0.130 M * 0.043 L
Moles NaOH = 0.00559 moles
Step 3: Calculate concentration of vinegar
Concentration = moles / volume
Concentration = 0.00559/ 0.00360 L
Concentration = 1.55 M
Step 4: Calculate mass of acetic acid in 1.30 qt sample
1.30 qt * 0.946353 L * 1.55 M *60.06 g/mol =114.53 grams
There is 114.53 grams of acetic acid in 1.30 qt of sample
Answer: Vapor pressure or equilibrium vapor pressure is the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed container. All liquids and solids have a tendency to evaporate or sublime into a gaseous form and all gases have a tendency to condense back to their liquid or solid form. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as volatile.
Vapour Pressure Formula
X solvent = the mole fraction of the solvent in the solution.
P solution = the vapour pressure of the solution.
P°solvent = the vapour pressure of the solvent.

Explanation:
Activation energy is the minimum required energy that a system must absorb before the reaction can begin.
<h3>What is Activation Energy? </h3>
In chemical reaction, activation energy is the minimal amount of energy necessary or required to get atoms or molecules to a state where they undergo chemical transformation.
In this chemical reaction process;
- Bonds are broken in the reaction and bonds are formed in the product.
