Question

Factors affecting the rate? in chemical kinetics

Answer 1

Explanation:

TOPIC:-

=> Reaction rate.

DEFINITION:-

=>The rate of reaction refers to the speed at which the products are formed from the reactants in a chemical reaction.

=>The rate of reaction or reaction rate is the speed at which reactants are converted into products. 

=>For example,

Wood combustion has a high reaction rate since the process is fast and rusting of iron has a low reaction rate as the process is slow.

$\huge\tt\fbox\purple{Answer}$

So,For this reaction rate we have some factors affecting it.

Those factors are,

=>Nature of the reaction.

• The rate of reaction is generally slower in liquids when compared to gases and slower in solids when compared to liquids.
• Size of the reactant also matters a lot.
• The smaller the size of reactant, the faster the reaction.

=>Effect of concentration on reaction rate.

• According to the collision theory, the rate of reaction increases with the increase in the concentration of the reactants.
• Time plays a major role in changing the concentration of reactants and products.
• Therefore, even time is a vital factor affecting the reaction rate.

=>Pressure factor

• Pressure increases the concentration of gases which in turn results in the increase of the rate of reaction.
• The reaction rate increases in the direction of less gaseous molecules and decreases in the reverse direction.

=>Solvent

• The rate of reaction also depends on the type of solvent. Properties of solvent and ionic strength highly affect the reaction rate.

=>Order

• The order of reaction manages how the reactant pressure or concentration affects the rate of reaction.

=>Electromagnetic Radiation

• Electromagnetic radiation is a form of energy and its presence at the chemical reaction may increase the rate of reaction as it gives the particles of reactants more energy.

=>Intensity of Light

• Even the intensity of light affects the rate of reaction. Particles absorb more energy with the increase in the intensity of light thereby increasing the rate of reaction.

Therefore, these are the factors affecting the reaction rate in chemical kinetic.

Answer 2

Answer:

hope i can help

Explanation:

some factors that affect the rate of reaction are:

temperature-increase in temperature increases the rate of reaction a particles gain more kinetic energy resulting in more successful collisions among them

surface area-increase in surface area(for example: turning Mgo into powder form)increases the rate of reaction as more particles are being exposed.

catalyst-this just speed up a chemical reaction without getting changed by the reaction before and after it.

concentration-increasing the concentration of reactant will lead to a faster reaction because there are more molecules that can react.
