What is the relationship between concentration and rate of reaction?
grigory [225]
<h3><u>Answer;</u></h3>

Directly proportional

<h3><u>Explanation;</u></h3>
  • <em><u>Concentration is one of the factors that determine the rate of a reaction. Reaction rates increases with increase in the concentration of the reactants, which means they are directly proportional.</u></em>
  • An increase in the concentration of reactants produces more collisions and thus increasing the rate at which the reaction is taking place. Therefore, <u>Increasing the concentration of a reactant increases the frequency of collisions between reactants and will cause an increase in the rate of reaction.</u>

A compound is 44.7% P and the rest O. Determine its emperical formula.
svet-max [94.6K]

Answer:  

P₅O₁₂

<em>Explanation:  </em>

Assume that you have 100 g of the compound.  

Then you have 44.7 g P and 55.3 g O.  

1. Calculate the <em>moles</em> of each atom  

Moles of P  = 44.7 × 1/30.97 = 1.443 mol Al  

Moles of O = 55.3 × 1/16.00 = 3.456 mol O  

2. Calculate the <em>molar ratios</em>.  

P: 1.443/1.443 =   1  

O: 3.456/1.443 = 2.395

3. Multiply by a number to make the ratio close to an integer

P:  5 × 1         =  5

O: 5 × 2.395 = 11.97

3. Determine the <em>empirical formula </em>

Round off all numbers to the closest integer.  

P:   5

O: 12

The empirical formula is <em>P₅O₁₂</em>.
