3. A flask is charged with 1.000 atm of A and allowed to react to form B and D according to the hypothetical gas-phase reaction A(g) (9)+D(g). The following data are collected: Time /s 0 2500 5000 7500 10.000 PA/ atm 1.000 0.947 0.895 0.848 0.803 (a) Using appropriate graphical analysis, determine whether the reaction is zero-order, or first-order, or second-order. (Need to plot three graphs on a computer for a zero-order reaction, a first-order reaction, and a second-order reaction. Please attach the data table and three graphs with the prelab. Ensure that graphs are labeled properly and that you indicate the correlation factor (Rvalue) for linearity on each graph) (b) Write down a general Rate Law and Integrated Rate Law (c) What is the rate constant? (d) What is the half-life
