Question

what would the rate of reaction be if the concentration of substance D was 0.0207 mol L-1 and the concentration of substance E was 0.0116 mol L-1?





Consider the hypothetical reaction

D(g) + E(g) ----------> F(g)

for which the following initial rate data has been obtained:


Expt. # [D]initial [E]initial Initial Rate

1 0.0102 mol L-1 0.0419 mol L-1 1.22 x 10-5 mol L-1 s-1

2 0.0306 mol L-1 0.0419 mol L-1 3.66 x 10-5 mol L-1 s-1

3 0.0306 mol L-1 0.0838 mol L-1 7.32 x 10-5 mol L-1 s-1

Answer 1

Find the rate law, then use the concentrations given to find the rate at that moment.
