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:
3H₂(g) + N₂(g) $\rightarrow$ 2NH₃(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) -R(H₂) = 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)
