Explanation:
The given data is as follows.
50 ml of , 50 ml of
And, it is known that at STP 1 mole of a gas occupies 22.4 L. Hence, moles present in 50 ml of gas are as follows.
(As 1 L = 1000 ml)
= moles
So, according to the given equation moles of
reacts with
moles of
.
Hence, moles of is equal to the moles of
and
.
Therefore, moles of =
moles
1 mole of = 22.4 L
moles =
= 50 ml of product
Thus, we can conclude that 50 ml of products if pressure and temperature are kept constant.
Answer:
Part a: The rate of the equation for 1st order reaction is given as
Part b: The integrated Rate Law is given as
Part c: The value of rate constant is
Part d: Concentration after 4000 s is 0.043 M.
Explanation:
By plotting the relation between the natural log of concentration of , the graph forms a straight line as indicated in the figure attached. This indicates that the reaction is of 1st order.
Part a
Rate Law
The rate of the equation for 1st order reaction is given as
Part b
Integrated Rate Law
The integrated Rate Law is given as
Part c
Value of the Rate Constant
Value of the rate constant is given by using the relation between 1st two observations i.e.
t1=0, M1=1.00
t2=120 s , M2=0.91
So k is calculated as
The value of rate constant is
Part d
Concentration after 4000 s is given as
Concentration after 4000 s is 0.043 M.
