I know this question has two parts, but it counts as one question. Can you please help with this. 

D. Concentrations of Reactants: Magnesium-Hydrocholoric Acid System
In many cases, if the variable being changed is concentration of chemical constituent has the effect of changimg the rate of a reaction.
Parameters of the experiment: four test tubes are acquired of varying concentrations of hydrochloric acid [HCI] consisting of lM, 3M, 4M, and
6M Magnesium metal [Mg] is placed in test tube and the time it takes for the Mg to dissolve is measure.
Lab Data (Observation):
Test Tube (1M HCI): 1.26 min/seconds
Test Tube (3M HCI): 51 seconds
Test Tube (4M HCI): 23 seconds
Test Tube (6M HCI): 5.6 seconds
Question-8 Calculate the rate for each test tube. For part. D use the concentration of Mg(s) at 0.05M. Rate A[Mg]/time
Question-9 Based on the data above what is the relationship between concentration and the rate of reaction?
