Which of the following equations correctly describes the relationship between the rate at which NO2 and Cl2 are consumed in the following reaction?

Question

2 NO2(g) + Cl2(g) → 2 NO2Cl(g)

A. -d(NO2)/dt = 1/2 [d(Cl2)/dt]
B. -d(NO2)/dt = 2 [d(Cl2)/dt]
C. -d(NO2)/dt = 2 [-d(Cl2)/dt]
D. -d(NO2)/dt = 1/2 [-d(Cl2)/dt]
E. -d(NO2)/dt = -d(Cl2)/dt

Answer 1

-d(NO2)/dt = 2 [-d(Cl2)/dt]

Answer 2

thx answer is correct
