Answer:
Explanation:
The formula we must use is given to us:
q is the energy, m is the mass, and L(vapor) is the latent heat of vaporization.
The energy is what we calculate and the mass is 2 kilograms. We need to find the latent heat of vaporization, which is on the table.
- We know the sample is copper.
- Find that element on the table, then the third box tells us it's latent heat of vaporization is 4730 kJ/kg
Now we know:
Substitute the values into the formula.
Multiply. Note that the kilograms (kg) will cancel each other out.
<u>9460 kilojoules</u> are required to vaporize 2 kilograms of copper.
<u>Answer:</u> The value of is 0.136 and is reactant favored.
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the chemical reaction between carbon monoxide and hydrogen follows the equation:
The expression for the is given as:
We are given:
Putting values in above equation, we get:
There are 3 conditions:
- When
; the reaction is product favored.
- When
; the reaction is reactant favored.
- When
; the reaction is in equilibrium.
For the given reaction, the value of is less than 1. Thus, the reaction is reactant favored.
Hence, the value of is 0.136 and is reactant favored.
