Hydrocarbons, compounds containing only carbon and hydrogen, are important in fuels.The heat of combustion of cyclopentane, C5H1
1 answer:
Answer : The balanced equation for the complete combustion of cyclopentane will be :
Explanation :
As we know that the hydrocarbons can undergo complete or incomplete combustion that depends on the amount of oxygen available.
Complete combustion : It takes place when there is a good supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon dioxide and water as a product.
The general reaction will be :
Incomplete combustion : It takes place when there is a poor supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon monoxide, carbon dioxide and water as a product.
The general reaction will be :
As per question, the complete combustion of cyclopentane react with oxygen to gives carbon dioxide and water as a product.
Therefore, the balanced chemical reaction will be :

Answer :
(a) The concentration of after 1.00 hr will be 0.0037 M
(b) The concentration of after 1.00 day will be 0.00060 M
Explanation :
(a) The expression for first order reaction is:
where,
= concentration of
at time 't' = ?
= concentration of
at time '0' = 0.0040 M
k = rate constant = (assuming the power of 10 from the correct source)
t = time = 1.00 hr = 3600 s (1 hr = 3600 s)
Now put all the given values in the above expression, we get:
Thus, the concentration of after 1.00 hr will be 0.0037 M
(b) The expression for first order reaction is:
where,
= concentration of
at time 't' = ?
= concentration of
at time '0' = 0.0040 M
k = rate constant =
t = time = 1.00 day = 86400 s (1 day = 86400 s)
Now put all the given values in the above expression, we get:
Thus, the concentration of after 1.00 day will be 0.00060 M
