Answer:

Fission

Explanation:

Nuclear reactions are broadly classified into fission and fusion reactions.

In nuclear fusion two lighter nuclei combine to form a heavy nucleus along with the release of a large amount of energy.

In contrast, fission reactions involve splitting of a heavy unstable nucleus into lighter nuclei along with the release of energy. Nuclear reactors work on the principle of nuclear fission which involves the breakdown of U-235 nucleus via the following equation:

₉₂U²³⁵ + ₀n¹ → ₅₆Ba¹⁴¹ + ₃₆Kr⁹² + 3₀n¹ + 200 MeV energy

The energy generated in nuclear power plants currently serve as a source of clean energy relative to that generated from coal powered plants. Therefore, as of right now energy from nuclear fission is the most feasible for human use.

As of now, the nuclear fission is the most feasible energy source for human use. All the nuclear power plants are based on the controlled nuclear fission reaction, where the unstable nucleus is bombarded with high speed neutrons, thus, splitting the nucleus into stable ones and releasing huge amount of energy. The nuclear fusion requires very high temperature, the temperature equal's to that of the sun. Hence, it is not feasible right now. As the technology advances, we will see advancement in other form of energies.

The gas arsine, AsH3, decomposes as follows: In an experiment at a certain temperature, pure AsH3(g) was placed in an empty, rig

bazaltina [42]

The equilibrium pressure of $H_{2}$ is 288 torr. and $K_{p}$ for this reaction is 0.786 atm.

from the reaction:- $2AsH_{3}$ ⇄ $2As + 3H_{2}$

initial concentration 392 torr. 0

at equilibrium. 392 - $2x$ . $3x$

and the final pressure in the flask = 488 torr.

Hence,

$( 392 - 2x ) + 3x = 488\\ x = 488-392\\x = 96 torr.$

The partial pressure of $H_{2}$ is 3 × 96 = 288 torr.

and $AsH_{3}$ is 392 - ( 2 × 96 ) = 392 - 192 = 200 torr.

Now, to find $K_{p}$ for this reaction, we will use $K_{p} = \frac{(P_{H_{2} })^{2} }{( P_{AsH_{3} } )^{2}}$

putting all the values, we get,

$K_{p} = \frac{(288)^{3} }{(200)^{2} }$

= 597.1968 torr.

= 0.786 atm. ( 1 atm = 760 torr. )

what do you mean by equilibrium?

Equilibrium in chemistry is the phase that exists when a chemical reaction and its opposite reaction happen at the same rates. This word's Latin origin dates back to the prefix aequi-, which means equal, and lbra, that indicates scale or balance.

Classify the possible combinations of signs for a reaction's ΔH and ΔS values by the resulting spontaneityA. ΔH is positive and

sergejj [24]

Explanation:

1. Spontaneous as written at all temperatures

C. When ΔH is negative and ΔS is positive, the sign of ΔG will always be negative, and the reaction will be spontaneous at all temperatures.

2. Spontaneous in reverse at all temperatures

A. When ΔH is positive and ΔS is negative, the sign of ΔG will always be positive, and the reaction can never be spontaneous.

3. Spontaneous as written above a certain temperature

B. ΔH is positive and ΔS is positive - an endothermic reaction (positive ΔH) that also displays an increase in entropy (positive ΔS). It is the entropy term that favors the reaction. Therefore, as the temperature increases, the TΔS term in the Gibbs free energy equation will begin to predominate and ΔG will become negative.

4. Spontaneous as written below a certain temperature

D. ΔH negative and ΔS is negative - When the reaction is exothermic (negative ΔH) but undergoes a decrease in entropy (negative ΔS), it is the enthalpy term which favors the reaction. In this case, a spontaneous reaction is dependent upon the TΔS term being small relative to the ΔH term, so that ΔG is negative. The freezing of water is an example of this type of process. It is spontaneous only at a relatively low temperature.
