Answer: The new volume of gas is 28.5 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 1.00 atm (at STP)
= final pressure of gas = 102.6 kPa = 1.01 atm (1 kPa= 0.0098 atm)
= initial volume of gas = 10.0 L
= final volume of gas = ?
= initial temperature of gas =
(STP)
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new volume of gas is 28.5 L
Answer : The rate of the reaction if the concentration of is doubled is, 0.006 M/s
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The balanced equations will be:
In this reaction, and
are the reactants.
The rate law expression for the reaction is:
As we are given that:
= concentration of
= 0.100 M
= concentration of
= 0.100 M
Rate = 0.0030 M/s
Now put all the given values in the above expression, we get:
Now we have to calculate the rate of the reaction if the concentration of is doubled.
Thus, the rate of the reaction if the concentration of is doubled is, 0.006 M/s
