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.
![Rate=k[A]^x[B]^y](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5Ex%5BB%5D%5Ey)
k= rate constant
For the given rate law:
![Rate=k[A]^1[B]^1](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5E1%5BB%5D%5E1)
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
![Rate'=k[2A]^1[B]^1](https://tex.z-dn.net/?f=Rate%27%3Dk%5B2A%5D%5E1%5BB%5D%5E1)
![Rate'=k[2]^1[A]^1[B]^1](https://tex.z-dn.net/?f=Rate%27%3Dk%5B2%5D%5E1%5BA%5D%5E1%5BB%5D%5E1)
![Rate'=[2]^1\times Rate](https://tex.z-dn.net/?f=Rate%27%3D%5B2%5D%5E1%5Ctimes%20Rate)
![Rate'=[2]\times Rate](https://tex.z-dn.net/?f=Rate%27%3D%5B2%5D%5Ctimes%20Rate)
b) The reaction is first order overall: False
The overall order is 1+1= 2.
c) k is the reaction rate constant: True
![Rate=k[A]^x[B]^y](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5Ex%5BB%5D%5Ey)
k= rate constant
d) The reaction is first order in [B]: True
For the given rate law:
![Rate=k[A]^1[B]^1](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5E1%5BB%5D%5E1)
x = 1= order with respect to A
e) The reaction is first order in [A]: True
For the given rate law:
![Rate=k[A]^1[B]^1](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5E1%5BB%5D%5E1)
y =1= order with respect to B
In order for a solute to dissolve it needs to fit in between the molecules of the solvent. When you stir the mixture it makes all the molecules move around making it more likely for the solute to find one of the gaps in the solvent needed to dissolve. In the case of lemonade, sugar is the solute and water is the solvent.
Answer: 1:8
Explanation: The ratio of hydrogen and oxygen by mass in water is 1:8. The atomic masses of H and O are 1 g/mol and 16 g/mol respectively.
