A concentration C (mol/L) varies with time (min) according to the equation C = 3.00 exp (-2.00t) (a) What are the units of 3.00 and 2.00? (b) Suppose the concentration is measured at t = 0 and t = 1 min. Use two-point linear interpolation or extrapolation to estimate C(t = 0.6 min) and t(C = 0.10 mollL) from the measured values, and compare these results with the true values of these quantities. (c) Sketch a curve of C versus t, and show graphically the points you determined in part (b).
