Question

Just as the depiction of stratospheric ozone threatens life on Earth today, its accumulation was one of the crucial processes that allowed life to develop in prehistoric times: 3O2(g) rightarrow 2O3(g) At a given instant, the reaction rate in terms of [O2] is 2.17 x 10-5 mol/L*s. What is it in terms of [O3]? Enter your answer in scientific notation. Express the rate of reaction in terras of the change in concentration of each of the reactants and products: 2D(g) + 3E(g) + F(g) rightarrow 2G(g) + H(g) When [D] is decreasing at 0.44 mol/L*s, how fast is [H] increasing?

Explanation / Answer

1)1.44 x 10 ^-5 mol/L.s 2) A 3)0.22 mol/L.s
