Explanation:
1)Mass of CO when 210.3 g of Fe produced.
Number of moles of 
in 210.3 g=
According to reaction, 2 moles of Fe are obtained from 3 moles of CO, then 3.76 moles of Fe will be obtained from : 
of CO that is 5.64 moles.
Mass of CO in 5.64 moles =
2)Mass of CO when 209.7 g of Fe produced.
Number of moles of in 209.7 g=
According to reaction, 2 moles of Fe are obtained from 3 moles of CO, then 3.75 moles of Fe will be obtained from : 
of CO that is 5.625 moles.
Mass of CO in 5.625 moles =
Answer: The given statement is true.
Explanation:
When we increase the amount of solvent which is water in this case then it means there will occur an increase in the molecules. Hence, there will be more number of collisions to take place with increase in number of molecules.
Therefore, more is the amount of interaction taking place between the molecules of a solution more will be its rate of hydrolysis.
Thus, we can conclude that the statement increasing the amount of water in which the sugar is dissolved will increase the frequency of collisions between the sucrose molecules and the water molecules resulting in an increase in the rate of hydrolysis, is true.
