<u>Answer:</u> The value of is
<u>Explanation:</u>
We are given:
Initial moles of ammonia = 0.0280 moles
Initial moles of oxygen gas = 0.0120 moles
Volume of the container = 1.00 L
Concentration of a substance is calculated by:
So, concentration of ammonia =
Concentration of oxygen gas =
The given chemical equation follows:
<u>Initial:</u> 0.0280 0.0120
<u>At eqllm:</u> 0.0280-4x 0.0120-3x 2x 6x
We are given:
Equilibrium concentration of nitrogen gas =
Evaluating the value of 'x', we get:
Now, equilibrium concentration of ammonia =
Equilibrium concentration of oxygen gas =
Equilibrium concentration of water =
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of is
Answer:
20.3 kJ of heat is absorbed when 9.00 g of steam condenses to liquid water.
Explanation:
Heat is being consumed during vaporization and heat is being released during condensation.
To vaporize 1 mol of water, 40.66 kJ of heat is being consumed.
Molar mass of water = 18.02 g/mol
Hence, to vaporize 18.02 g of water , 40.66 kJ of heat is being consumed.
So, to vaporize 9.00 g of water, of heat or 20.3 kJ of heat is being consumed
As condensation is a reverse process of vaporization therefore 20.3 kJ of heat is absorbed when 9.00 g of steam condenses to liquid water.
