Please answer number 2: Data from a batch experiment for the elementary reaction A --> 2B, are given below. Use these data to estimate a value for the reaction rate constant. Use Excel to plot the data, show the graphs, and use the linear regression.

a) What are the units for k ? b) The moleeular weight for the compound is 120g/mol. Rewrite the rate expression with units of mol cm3:51 c) What are the units for k in the expression written for part b? 2. Data from a batch experiment for the elementary reaction, A2B, are given below. Use these data to cstimate a value for the reaction rate constant Use Excel to plot the data, show the graphs, and use linear 3. Many municipalitics have considered using polyphosphates in an attempt to control load corrosion in drinking water systems. Some studies indicate that polyphosphates can inhibit lead corrosion and some studies suggest polyphosphates can accelerate lead corrosion. One aspect of the process that is known, that polyphosphates are not stable in water. The hydrolysis of pyrophosphate, for example, can be represenled as
