Problem

Consider the following hypothetical reaction

4A (g) + 2B (g) → 3C (g) + D (g)

Which of the following statement(s) is/are correct?

i. The rate B disappears is twice (2 times) the rate that D appears.

ii. The rate A disappears is twice (2 times) the rate that B disappears.

iii. The rate C appears is one third (1/3 times) the rate that D appears.

 

A. i only

B. ii only

C. i and ii

D. ii and iii

E. i and iii
