<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by
For a general chemical reaction:
The is written as:
There are 3 conditions:
- When
; the reaction is product favored.
- When
; the reaction is reactant favored.
- When
; the reaction is in equilibrium.
At equilibrium, the ratio of concentration of reactants to the concentration of products is equal to 1.
At equilibrium, the rate of forward reaction is equal to rate of backward reaction.
Hence, the correct answer is Option D.
<u>Answer:</u> The amount of heat absorbed by the solution is 2.795 kJ
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
Density of water = 1 g/mL
Volume of water = [70 + 70] = 140 mL
Putting values in above equation, we get:
To calculate the heat absorbed, we use the equation:
where,
q = heat absorbed
m = mass of water = 140 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature =
Putting values in above equation, we get:
Hence, the amount of heat absorbed by the solution is 2.795 kJ
