Which answer does not describe the following reaction? no (g) + o2 (g) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. 2 no2 (g) (1) the reaction is in dynamic equilibrium. (2)the reaction does not go to completion. (3)the reaction is reversible. (4)the concentration of reactants and products will be equal.

“(4) The concentration of reactants and products will be equal” does not describe the reaction.

2NO(g) + O₂(g) ⇌ 2NO₂(g)

The concentrations will almost certainly not be equal.

The reaction is a reversible dynamic equilibrium. There is always some NO and NO₂ present at equilibrium, so the reaction does not go to completion.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

i think its 100.

hope this !
