1) Determine the Kc for the following experimental conditions:
compound A+compound B --> Compund D
Compound: A B
M 0.003 0.0023
Volume used: 5 mL 8 mL
Total volume = 25 mL, using graph 2 and a %T of 24 for compund D molecular weight compund D = 535 g/mol
2) Determine Kc for compound D at a %T of 65 with the same initial concentrations as question 1 and graph 2
3) A group used 15 mL of compound Band 8 mL of compound A with the total volume of 2.5 mL and the %T was 5. Using graph 2 determine Kc.
The chart for graph 2 gives this information:
y = absorbance= 0.069, 0.324, 0.594, 0.864, 1.134, 1.404, 1.674
x = concentration (mg/mL) respectively= 0.01, 0.06, 0.11, 0.16, 0.21, 0.26, 0.31.
There is a y=5.3679x + 0.0073 equation also.
