Question

In reaction 2NO+O2=2NO2;if rate of disappearance of O2 is16gm/min, then the rate of appearance of NO2 is

Answer 1

Given equation: 2N2O5 = 4NO2 + O2

Rate of disappearence of N2O5×1/2 = 1/4×rate of formation of No2

Disappearence of N2O5 =  2×1/4×2.8×10power-3

1.4×10power-3

Explanation: However, we still write the rate of disappearance as a negative number.

Also, if you think about it, a negative rate of disappearance is essentially a positive rate of appearance."
