Geologic Time Scale Time Period Duration (Millions of Years Ago)

Cenozoic 66-0

Mesozoic 252-66

Paleozoic 541-252

According to the scale, what time period are we in today?

a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of these

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
