Answer:1.
2. The rate constant (k) for the reaction is
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
x = order with respect to
y = order with respect to
n = x+y= Total order
1. a) From trial 1: (1)
From trial 2: (2)
Dividing 2 by 1 :
therefore x=1.
b) From trial 2: (3)
From trial 3: (4)
Dividing 4 by 3:
therefore
2. to find rate constant using trial 1:
Answer: The reaction is first order overall.
Explanation: Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
For the given rate law:
x = 1= order with respect to A
y =1= order with respect to B
n =( x+y)= (1+1) = 2 = Total order
a) If [A] is doubled, the reaction rate will increase by a factor of 2: True
b) The reaction is first order overall: False
The overall order is 1+1= 2.
c) k is the reaction rate constant: True
k= rate constant
d) The reaction is first order in [B]: True
For the given rate law:
x = 1= order with respect to A
e) The reaction is first order in [A]: True
For the given rate law:
y =1= order with respect to B
