For the chemical reaction N2(g) + 3H2 (g) ⇌ 2NH3 (g) The correct option is –

Question : For the chemical reaction

N₂(g) + 3H₂ (g) ⇌ 2NH₃ (g)

The correct option is –

Answer : from all above options the correct answer is option “3”

For the reaction

N₂(g) + 3H₂ (g) ⇌ 2NH₃ (g)

Rate of reaction is given by –

explanation of answer : as we know that the rate of reaction can be defined as the speed of any reaction by which that chemical reaction happened. and the speed of reaction depends on many things like concentration of products per unit time etc. and when we decrease concentration of products per unit time then the reaction speed will also decrease. for the reaction given in question (N₂(g) + 3H₂ (g) ⇌ 2NH₃ (g))  the speed of reaction can be shown same as given in option 3 , that is why we have marked this correct answer.
