Answer the following questions based on the reaction below. Report all answers to three significant figures.


K2SO4(aq) + Sr(NO3)2(aq) → SrSO4(s) + 2KNO3(aq)

The concentration of K2SO4 is 0.222 M at the start of the reaction, and 0.135 M after 122 seconds. The initial concentrations of the products are zero.



1. What is the average rate of reaction (in M/min) over this time period?

2. What is the average rate of change (in M/min) of K2SO4 in the first 122 seconds.

3. What is the average rate of change (in M/min) of KNO3 in the first 122 seconds.

4. What is the concentration (in M) of KNO3 after 122 seconds.
