Rates of Change in Chemical Reactions
1. For the reaction A + 3B à 2C, how does the rate of disappearance of B compare to the rate of production
of C?
a. the rate of disappearance of B is 1/2 the rate of appearance of C
b. the rate of disappearance of B is 3/2 the rate of appearance of C
c. the rate of disappearance of B is 2/3 the rate of appearance of C
d. the rate of disappearance of B is 1/3 the rate of appearance of C
2. For the reaction 2A + 3B → 4C + 5D, the rate of the reaction in terms of ΔA would be written as:
a. –ΔA/Δt.
d. +1/2 ΔA/Δt.
b. –1/2 ΔA/Δt.
e. –2 ΔA/Δt.
c. +ΔA/Δt.
3. For the reaction 2A + 3B → 4C + 5D, the rate of the reaction in terms of ΔB would be written as
a. –ΔB/Δt
d. +1/3 ΔB/Δt
b. +ΔB/Δt
e. –3 ΔB/Δt
c. –1/3 ΔB/Δt
4. For the reaction 2A + 3B → 4C + 5D, the rate of the reaction in terms of ΔC would be written as
