Answer:

The answer is 0.01 M

Explanation:

The problem is solved by applying the expression for ionic product of water as follows:

Kw = [H₃O⁺] [OH⁻]

Where Kw is the ionic product of water and it is 1.10⁻¹⁴ M at⁴ 25ºC. As [OH⁻]= 1.10⁻¹² M, [H₃O⁺] will be:

[H₃O⁺]= Kw/ [OH⁻]= 1.10⁻¹⁴M/1.10⁻¹²M= 0.01 M

Speeds up the reaction but does not change k
notka56 [123]
The answer is catalyst.

A catalyst is characterized by acceleration the rate of a chemical reaction but not modifiy the equilibrium, which is what k represents (the constant of equilibrium of the reaction).

The catalyst manages that the reaction goes through a different pathway, with a lower activation energy, so the transition compound is reached faster and the whole reaction goes faster, but the final species and their equilibriium concentrations do not change.

What is the relationship between particle size and wheathering rate
Olegator [25]

The relationship between particle size and wethering rate as the errosion occurs on the surface area.

So wethering is proportional to the particles size of elements as more smaller the particles and more swiftly particles are surrounded erosion specially chemical occurrs weathering that acts as more aspace in rocks with small particle sizes.
