Question

Which of the following would increase the rate of this chemical reaction N2(g) + 3H2(g) 2NH3(g)
Reduce the temperature
Decrease the volume
Introduce a catalyst


I only

I and II

II and III

III only

Answer 1

for seeing the effect of temperature, u should know wat kind of reaction it is,endothermic or exothermic?

Answer 2

2 increases the likelyhood that the molecules or atoms will hit because they are in a more confined space, and 3 lowers the activation energy required for the reaction to take place. So between the 2 of them it will increase the rate of the reaction.

Answer 3

Yes, zbay is correct. II and III.

Lowering temperature will slow down the reaction rate.
Decreasing volume, increases pressure so more frequent collisions.
Catalysts lowers activation energy, so reaction will occur faster.
