Answer:
2.4506 x
Explanation:
move decimal point to the right 1 time : 24506
24506 becomes 2.4506
count how many numbers after decimal point and that becomes b
b = 4

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
Explanation:
It is known that more linearly the atoms are arranged in a carbon chain more will be its melting point. This is because then more surface area has been occupied by the molecule and in order to break all the bonds, heat energy has to reach to the entire surface area.
As a result, melting point of the compound will be high. On the other hand, more is the branching present in a carbon chain less will be the surface area occupied by it. Hence, smaller will be its melting point.
Therefore, in the given structures of () as the branching increases there occurs a decrease in melting point.
