Consider the chemical equation: N 2 ( g ) + 3 H 2 ( g ) ⟶ 2 N H 3 ( g ) . The rate of reaction can be expressed in terms of the time derivative of the concentration of N 2 ( g ) , H 2 ( g )

Question

Consider the chemical equation: N 2 ​ ( g ) + 3 H 2 ​ ( g ) ⟶ 2 N H 3 ​ ( g ) . The rate of reaction can be expressed in terms of the time derivative of the concentration of N 2 ​ ( g ) , H 2 ​ ( g ) , or N H 3 ​ ( g ) . Identify the correct relationship among the rate expressions.

N 2 ​ + 3 H 2 ​ → 2 N H 3 ​ R a t e = − a 1 ​ d t d [ A ] ​ So, R a t e = − d t d [ N 2 ​ ] ​ = − 3 1 ​ d t d [ H 2 ​ ] ​ = 2 1 ​ d t d [ N H 3 ​ ] ​
