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.
