Answer:
The concentration is 
Explanation:
From the question we are told that
The absorbance is 
The length is 
Generally absorbance is mathematically represented as

where
is the molar absorptivity of FeSCN2 with a value 
and
is the equilibrium concentration of FeSCN2
So

substituting values


Answer:
The formula for calculating pH is pH=−log[H_3O+ ]
pH is the negative logarithm (to base 10) of hydronium ion concentration
The pH Formula can also be expressed as
PH= - log[H+ ]
because it can influence how frequently and sufficiently the particles collide depending on the space it has to do so, for example a large surface area would be have a slower rate of reaction and a lower temperature. (the rate of reaction in terms of concentration, it is diffused from high to low)
Answer:
The role that chlorine atoms have in increasing the depeltion rate ozone is that Cl acts as a catalyst.
Explanation:
- From the two steps of the reaction:
- O₃ + Cl· → ClO· + O₂
- ClO· + O → Cl· + O₂
- The overall reaction is: O₃ + O → 2O₂
- It is clear that ClO· is an intermediate that has been produced within the first step and has been consumed in the second step.
- Also, Cl· is considered as a catalyst in this reaction that it has been consumed in the first step and has been produced in the second step, which means that it does not get up in the reaction, that is the main characteristic of the catalyst.
- The catalyst usually increases the rate of the reaction by lowering its energy of activation (The minimum energy that is required to initiate the reaction) by proceeding the reaction in an alternative pathway <em>(changing the reaction mechanism)</em>.
- Hence, the role affecting the reaction rate that chlorine atoms have in increasing the depletion rate of ozone that it acts as a catalyst and does not get used up in the reaction.
