Answer #1

4 NH3 + 5 O2 -------> . 4 NO + 6 H2O

first write rate equation

rate = 1/4 (-d[NH3] / dt) = 1/5 (-d[O2] /dt) = 1/4 (+d[NO] / dt) = 1/6 (+d[H2O] / dt

here -ve sign indicate the decrease in concentration

+ve charge in dicate the increase in concentration

from this expression we can answer this question

correct answer is d. The rate of (NO) appearance is equal to 1.25 times the rate of oxygen disappearance

we will prove it from above equation

1/4 (+d[NO] / dt) = 1/5 (-d[O2] /dt)

(+d[NO] / dt) = 4/5  (-d[O2] /dt)

(+d[NO] / dt) = 1.25 (-d[O2] /dt)
