Question

Question5 Consider the following reaction: A + B products. The rate law was found to be rate k[ A ][ B ]2. a. What is the order with respect to A? (number) b. What is the order with respect to B? (number) c. What is the overall order of the reaction? (number) d. If the concentration of A is doubled while the concentration of B is kept constant, the rate of the reaction would by a factor of e. If the concentration of B is doubled while the concentration of A is kept constant, the rate of the reaction would by a factor of f. If the concentration of B is doubled while the concentration of A is halved, the rate of the reaction would by a factor of

Explanation / Answer

a)
order of A = power of A = 1
Answer: 1

b)
order of B = power of B = 2
Answer: 2

c)
over all order = sum of all orders = 1 + 2 = 3
Answer: 3

d)
doubling A will double the rate as order of A is 1
Answer: increase, 2

e)
doubling B will double the rate as order of B is 2
Answer: increase, 4

f)
doubling B will double the rate as order of B is 2
halfing A will half the rate as order of A is 1

overall effect increasing 1.5 times
Answer: increase, 1.5
