Is rate = k[NO]2[O2]. The following mechanisms have been proposed: I. 2 NO(g) + O2(g) → 2 NO2(g) II.2 NO(g) ⇌ N2O2(g)[fast] N2O2(g) + O2(g) → 2 NO2(g) [slow] III.2 NO(g) ⇌ N2(g) + O2(g)[fast] N2(g) + 2 O2(g) → 2 NO2(g) [slow]

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b

Type the letter that represents the correct location for each particle type below.

Select the correct answer from each drop-down menu. describe what happens to a carbon-11 atom when it undergoes positron emission. the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
