Given the initial rate data for the reaction a + b –––> c, determine the rate expression for the reaction.
[a], m [b], m δ [c]/ δ t (initial) m/s 0.215 0.150 5.81 x 10–4 0.215 0.300 1.16 x 10–3 0.430 0.150 2.32 x 10–3
a) (δ[c]/δt) = 1.80 x 10–2 m –1 s –1 [a][b]
b) (δ[c]/δt) = 3.60 x 10–2 m –1 s –1 [a][b]
c) (δ[c]/δt) = 1.20 x 10–1 m –2 s –1 [a][b]2
d) (δ[c]/δt) = 5.57 x 10–2 m –3 s –1 [a]2 [b]2
e) (δ[c]/δt) = 8.37 x 10–2 m –2 s –1 [a]2 [b]
