are 
Solution : Given,
Mass of tablet = 1000 mg
Volume of water = 0.200 L
The given formula will be,

Now we have to calculate the reaction rate at different temperatures and reaction time.




Therefore, the reaction rate at
are 
Dissolve means a mixture of chemicals combine.
Example: salt and water you put salt in water stir and the salt dissolve
