techniques: (a) Standard addition, (b) External
calibration, and (c) Internal calibration: Draw a
picture of what each graph would look like, describe each
technique, and give a reason why each might be used for
quantification (an advantage of each).
*just wants a general example plot, not data is provided for
this problem.*
Explain Thomas model and the parameters (A, B, C and D).
Discuss
Calibration and Validation process and why do you need
Excel-based Solver for
Calibration. Is Thomas model a simulation model? Explain. Is it
conceptual,
physical or empirical model?
The reversible chemical reaction A+B⇌C+D has the following
equilibrium constant: Kc=[C][D]/[A][B]=5.4
PART A:
Initially, only A and B are present, each at 2.00 M .
What is the final concentration of A once equilibrium is
reached?
Express your answer to two significant figures and include the
appropriate units.
PART B:
What is the final concentration of D at equilibrium if the
initial concentrations are [A] = 1.00 M and [B] = 2.00
M ?
Express your answer to two significant...
