What does the concentration of reactants to affect the reaction rate

1 answer:

6 0

Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate

<h3>What is concentration?</h3>

A solution is made up of two components, solute and solvent. In chemistry, we define the concentration of solution as the amount of solute dissolved in the solution.

Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.

Hence, Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate.

How many moles are in 42.1 grams of NaCl?

vovikov84 [41]

Answer:

0.71

Explanation:

The molecular mass of NaCl is, 23+35.5

= 58.5

1 mole means molecular mass (in gram)

In 58.5 gm NaCl there is 1 mole.

So, 42.1 gm NaCl contains 42.1/58.5 =0.71 moles.

Metals react with oxygen to give oxides with the general formula MxOy. What is a balanced chemical equation for the reaction of

katovenus [111]

Answer: $4Fe+3O_2\rightarrow 2Fe_2O_3$

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here iron is having an oxidation state of +3 called as $Fe^{3+}$ cation and oxide $O^{2-}$ is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $Fe_2O_3$ .

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$2Fe+3O_2\rightarrow 2Fe_2O_3$
