0.124 M
Explanation:
The reaction obeys second-order kinetics:
According to the integrated second-order rate law, we may rewrite the rate law in terms of:
Here:
is a rate constant,
is the molarity of the reactant at time t,
is the initial molarity of the reactant.
Converting the time into seconds (since the rate constant has seconds in its units), we obtain:
Rearranging the integrated equation for the amount at time t:
We may now substitute the data:
Answer : The volume of the hydrogen at STP is, 36.8 mL
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 751 torr
= final pressure of gas at STP = 760 torr
= initial volume of gas = 40.0 mL
= final volume of gas at STP = ?
= initial temperature of gas =
= final temperature of gas at STP =
Now put all the given values in the above equation, we get:
Therefore, the volume of the hydrogen at STP is, 36.8 mL
