What is the activation energy for the formation of OZONE? 14 kj 406 kj 392 kj none of these the decomposition of dinitrogen pentoxide is described by the chemical equation N_2O_5 (g) rightarrow 4 NO_2(g) O_2(g) If the rate of disappearance of N_2O_5 is equal to 1. 40 mole/min at a particular moment, what is the rate of appearance of NO_2 at that moment? 1.40 mole/min 5.60 mole/m ln 2.80 mole/min 0.700 mole/min Which term describe the measure of the decrease in the concentration of a product per unit time? Reactant energy reaction time reaction rate kinetics the slowest step in a reaction mechanism is called the step. Rate-determining elementary rate law termination Which general rate law below corresponds to an elementary bimolecular reaction? Rate = k [A]^2 Rate = k [B] Rate = k [A] [B]^2 Rate = k[A] [B] [C] [D] Which one of the following statements does not describe the equilibrium state? The rate of the forward reaction is equal to the rate of the reverse reaction. the concentration of the reactants and products reach a constant level. The concentration of the reactants is equal to the concentration of the products.

Explanation / Answer

16.

The activation energy is 406 kJ

17.

The rate of appearance of NO2 is twice the rate of disappearance of N2O5 = 2.80 mol/min

18.

reaction rate

19.

rate determining step

20.

for bimolecular reaction order is 2. rate = k[A]2

21.

The concentration of reactants and products will remain constant.
