# Problem: Consider the following reaction: 2 NO(g) + 5 H2(g) → 2 NH3(g) + 2 H2O(g). A reaction mixture initially contains 5 moles of NO and 10 moles of H2. Without doing any calculations, determine which of the following best represents the mixture after the reactants have reacted as completely as possible.a. 1 mol NO, 0 mol H2, 4 mol NH3, 4 mol H2Ob. 0 mol NO, 1 mol H2, 5 mol NH3, 5 mol H2Oc. 3 mol NO, 5 mol H2, 2 mol NH3, 2 mol H2Od. 0 mol NO, 0 mol H2, 4 mol NH3, 4 mol H2O

###### FREE Expert Solution

2 mol NO = 2 mol NH3

5 mol H2 = 2 mol NH3 → smaller ratio

###### Problem Details

Consider the following reaction: 2 NO(g) + 5 H2(g) → 2 NH3(g) + 2 H2O(g). A reaction mixture initially contains 5 moles of NO and 10 moles of H2. Without doing any calculations, determine which of the following best represents the mixture after the reactants have reacted as completely as possible.
a. 1 mol NO, 0 mol H2, 4 mol NH3, 4 mol H2O
b. 0 mol NO, 1 mol H2, 5 mol NH3, 5 mol H2O
c. 3 mol NO, 5 mol H2, 2 mol NH3, 2 mol H2O
d. 0 mol NO, 0 mol H2, 4 mol NH3, 4 mol H2O
