Question

Part A

There are six different reactions you can access in the simulation using the drop-down menu. Which of the following are second-order reactions?

Check all that apply.

Check all that apply.

C2H6→2CH3

2N2O5→4NO2+O2

2N2O→2N2+O2

2HI→H2+I2

2NO2→2NO+O2

Answer 1

The elementary reactions are follows: 2. 2 N20 -4 NO2 +O2 3.2 HI-H, +I, In the first recation, one reactant molecule is involved in the reaction. Thus, it is a first order reaction Among these reactions, Decomposition of N2O, s a first order reaction. Because the rate of the reaction depends on the concentration of N,O,

The elementary recation of dissociation of HI is a second - order reaction. Decomposition of N2O is a first order reaction. Because the rate of the reaction depends on the concentration of N2O The elementary reaction of decomposition of NO, is a second order in [NO] Therefore, the reactions 3 and 5 are only second order reactions
