±reaction order
for the reaction a+b+c→d+e , the initial reaction rate was measured for various initial concentrations of reactants. the following data were collected:
trial [a]
(m ) [b]
(m ) [c]
(m ) initial rate
(m/s )
1 0.10 0.10 0.10 3.0×10−5
2 0.10 0.10 0.30 9.0×10−5
3 0.20 0.10 0.10 1.2×10−4
4 0.20 0.20 0.10 1.2×10−4
part a what is the reaction order with respect to a? 2
part b what is the reaction order with respect to b? 0
part c what is the reaction order with respect to c? 1
part d what is the value of the rate constant k for this reaction?
k =
3.0×10−2 m−2⋅s−1
part e given the data calculated in parts a, b, c, and d, determine the initial rate for a reaction that starts with 0.75 m of reagent a and 0.90 m of reagents b and c? express your answer to two significant figures and include the appropriate units. indicate the multiplication of units explicitly either with a multiplication dot or a dash.
