Consider the reaction: AB As the reaction proceeds, the concentration of A drops from 0.625 M to 0.100 Min 11.6 seconds. What is
1 answer:
Answer:
0.045 M/s
Explanation:
Given:
Initial concentration of A = 0.625 M
Final concentration of A = 0.100 M
Total time taken for the change of concentration = 11.6 seconds
The average rate of reaction is calculated as:
=
on substituting the respective values, we get
=
or
The average rate of reaction = 0.045 M/s

Answer:
The average pressure in the container due to these 75 gas molecules is
Explanation:
Here Pressure in a container is given as
Here
- P is the pressure which is to be calculated
- ρ is the density of the gas which is to be calculated as below
Here
mass is to be calculated for 75 gas phase molecules as
Volume of container is 0.5 lts
So density is given as
is the mean squared velocity which is given as
Here RMS is the Root Mean Square speed given as 605 m/s so
Substituting the values in the equation and solving
So the average pressure in the container due to these 75 gas molecules is
