Answer:
c. 0.750 atm .
Explanation:
Hello!
In this case, since the two vessels have different volume, we can see that the gas is initially at 3.00 atm into the 1.00-L vessel, but next, it is allowed to move towards the 3.00-L vessel, meaning that the final volume wherein the gas is located, is 4.00 L; therefore, we use the Boyle's law to compute the final pressure:
Therefore the answer is c. 0.750 atm .
Best regards!
In this reaction 50% of the compound decompose in 10.5 min thus, it is half life of the reaction and denoted by symbol .
(a) For first order reaction, rate constant and half life time are related to each other as follows:
Thus, rate constant of the reaction is .
(b) Rate equation for first order reaction is as follows:
now, 75% of the compound is decomposed, if initial concentration is 100 then concentration at time t
will be 100-75=25.
Putting the values,
On rearranging,
Thus, time required for 75% decomposition is 21 min.
