The controlled fusion reaction is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a nucleus. The mass of the new nucleus is slightly less than the sum of its components b an amount known as binding energy.
B. 1 kiloparsec
C. 1 light-year
D. 1 AU
The distance between the Earth and the Sun is approximately 1 AU (Astronomical Unit). Therefore, option D is correct.
One AU is defined as the average distance between the Earth and the Sun, which is about 93 million miles (150 million kilometers). It is a convenient unit of measurement for distances within our solar system.
A parsec is a unit of distance used for objects outside our solar system, equal to approximately 3.26 light-years. One kiloparsec is equal to 1,000 parsecs, or approximately 3,260 light-years. Therefore, neither A nor B is the correct answer.
A light-year is the distance that light travels in one year, which is approximately 5.88 trillion miles (9.46 trillion kilometers). Therefore, C is also not the correct, as the distance between the Earth and the Sun is much less than one light-year.
Therefore, the correct answer is D. 1 AU

The relationship between concentration and rate of reaction is directly proportional. As the concentration of reactants increases, the rate of the reaction also increases.
The rate of a chemical reaction is determined by the collision of reactant particles. When the concentration of reactants is higher, there are more particles per unit volume, increasing the likelihood of successful collisions. More collisions lead to more effective collisions, where the particles have sufficient energy and proper orientation to form products.
As a result, the reaction proceeds at a faster pace. This direct relationship between concentration and rate of reaction is described by the rate law of the specific reaction. The greater the concentration of the reactants, the more rapid the reaction will occur.
Concentration and rate of reaction are directly proportional; an increase in concentration leads to a corresponding increase in the reaction rate.
