The Production of Nitric Oxide Is Governed by the Following

The production of nitric oxide is governed by the following reaction: ​
4NH ₃ ( g ) + 5O ₂ ( g ) → 4NO( g ) + 6H ₂ O( g ) .
​
If the rate at which NO is produced is 6.35 × 10 ^{− 2} mol L ^{− 1} s ^{− 1} , at what rate is O ₂ consumed?

A) 8.29 × 10 ^{− 3} mol L ⁻¹ s ^{− 1}
B) 1.59 × 10 ^{− 2} mol L ⁻¹ s ^{− 1}
C) 6.35 × 10 ^{− 2} mol L ⁻¹ s ^{− 1}
D) 7.94 × 10 ⁻² mol L ⁻¹ s ^{− 1}
