Answer:
E) rate of appearance of C = 0.45 M/s
rate of the reaction = 0.15 M/s
Explanation:
2A + B → 3C
Writing rate law for the reaction:
<u>Rate of reaction</u> = -
= -
= 
→ equation 1
Given that the rate of disappearance of A is 0.3 M/s
⇒ -
= 0.3 M/s
⇒Rate of reaction = - 
=
×0.3 M/s
⇒<u>Rate of reaction = 0.15 M/s</u>
From equation 1,
= - 
=
×0.3 M/s
⇒
= 0.45 M/s
or <u>the rate of appearance of C = 0.45 M/s</u>
