Answer:
48%
Explanation:
Based on Gay-Lussac's law, the pressure is directly proportional to the temperature. To solve this question we must assume the temperature increases and all CO2 remains without reaction. The equation is:
P1T2 = P2T1
<em>Where Pis pressure and T absolute temperature of 1, initial state and 2, final state of the gas:</em>
P1 = 10.0atm
T2 = 1420K
P2 = ?
T1 = 730K
P2 = 10.0atm*1420K / 730K
P2 = 19.45 atm
The CO2 reacts as follows:
2CO2 → 2CO+ O2
Where 2 moles of gas react producing 3 moles of gas
Assuming the 100% of CO2 react, the pressure will be:
19.45atm * (3mol / 2mol) = 29.175atm
As the pressure rises just to 24.1atm the moles that react are:
24.1atm * (2mol / 19.45atm) = 2.48 moles of gas are present
The increase in moles is of 0.48 moles, a 100% express an increase of 1mol. The mole percent that descomposes is:
0.48mol / 1mol * 100 = 48%
Potential Chemical energy
Explanation:
Potential Chemical energy is stored in a fossil fuel and released in the form of kinetic heat energy when it is burnt.
Potential energy is the energy at rest in a body. It is that energy when no change is happening to a body. There are different forms of potential energy. A good example in fossil fuels is chemical energy.
Kinetic energy of a body is the energy due to the motion of a body. It occurs when particles of a medium are agitated. An example of kinetic energy in fossil fuel occurs when it is burnt.
- the formative process of a fossil fuel stores chemical energy.
- the process prevents energy rich carbon atoms from being converted back into nature by decomposers.
- the hydrocarbon chain stores chemical energy
- the energy is released when the molecules are burnt and they form heat energy, a form of thermal energy.
