For the exothermic reaction 2NO(g) → N2(g)+O2(g)
- A
Is independent of temperature
- B
Increases as temperature increases
- C
Decreases as temperature increases
- D
Varies with the addition of N2 and O2
In general, for an exothermic reaction, the reaction rate decreases as the temperature increases. This is because an increase in temperature provides more energy to the reactant's molecules, leading to a higher number of collisions and more effective collisions.
This option is not correct because the reaction rate of an exothermic reaction does depend on the temperature.
This option is also incorrect because, for an exothermic reaction, the reaction rate generally decreases as the temperature increases.
In general, for an exothermic reaction, the reaction rate decreases as the temperature increases. This is because an increase in temperature provides more energy to the reactant's molecules, leading to a higher number of collisions and more effective collisions.
The presence or addition of N2 or O2 does not directly influence the relationship between temperature and reaction rate for this exothermic reaction.
