Question

Part A

Consider the reaction

2H3PO4→P2O5+3H2O

Using the information in the following table, calculate the average rate of formation of P2O5 between 10.0 and 40.0 s.

Time (s)	0	10.0	20.0	30.0	40.0	50.0
[P2O5] (M)	0	3.00×10−3	6.00×10−3	7.80×10−3	9.00×10−3	9.60×10−3

Express your answer numerically in molar per second.

Rate of formation of P2O5 =		M/s

Part C

Consider the reaction

5Br−(aq)+BrO−3(aq)+6H+(aq)→3Br2(aq)+3H2O(l)

The average rate of consumption of Br− is 1.35×10⁻⁴M/s over the first two minutes. What is the average rate of formation of Br2 during the same time interval?

Express your answer numerically in molar per second to three significant figures.

Rate of formation of Br2 =		M/s
