Ammonia Gas (NH₃) Is Produced from Hydrogen and Nitrogen Gas $\rightarrow$

Ammonia gas (NH₃) is produced from hydrogen and nitrogen gas according to the following reaction: 3 H₂(g) + N₂(g) $\rightarrow$ 2 NH₃(g)
If the rate of production of ammonia is R(NH₃) , what is the rate of loss of hydrogen and nitrogen gas, respectively?

A) (-R(H₂) = 2/3 R(NH₃) ; -R(N₂) = 1/2 R(NH₃) )
B) (-RH₂) = 3/2 R(NH₃) ; -R(N₂) = 2 R(NH₃) )
C) (-R(H₂) =3/2 R(NH₃) ; -R(N₂) = 1/2 R(NH₃)
D) (-R(H₂) = 2/3 R(NH₃) ; -R(N₂) = 2 R(NH₃) )
E) (-R(H₂) =R(NH₃) ; -R(N₂) = R(NH₃) )
