The reaction 2 no(g) + o2(g) → 2 no2(g) was studied, and the following data obtained, where the rate is the following. rate = − d[o2] dt [no]0 (molecules/cm3) [o2]0 (molecules/cm3) initial rate (molecules·cm−3·s−1) 1.12 ✕ 1018 1.12 ✕ 1018 2.24 ✕ 1016 3.36 ✕ 1018 1.12 ✕ 1018 2.02 ✕ 1017 2.80 ✕ 1018 2.80 ✕ 1018 3.53 ✕ 1017 what would be the initial rate for an experiment where [no]0 = 6.24 ✕ 1018 molecules/cm3 and [o2]0 = 7.36 ✕ 1018 molecules/cm3?
