Question

For the reaction below, initially, 3.5 mol of NH3 is placed in a 4.0 L reaction chamber. After 3.0 minutes only 1.6 moles of NH3 remain.

SHOW ALL YOUR WORK.

4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(g)

a. Calculate the average rate of reaction with respect to NH3.

b. Calculate the average rate at which H2O is being formed.

c. Calculate the average rate at which O2 is being consumed.

Answer 1

a) Average rate of reaction of $NH_3$

$=2.5×10^{−3} M/S$

b) $1.8×10^{-3}M/s$

c) $8.4×10^{-6}M/s$
