Namme Section 2 EX PERIMENT 2 3 Pre-Laboratory Questions 1. The kinetics for the reaction 2 A 3 B C 2 D were studied at 20°C, and the following data were obtained by monitoring the rate of consumption of A. If it takes t seconds for A to be consumed, the initial rate for the consumption of A is equal to the initial concentration of A divided by the product of the time required for A to be consumed and the stoichiometric coefficient of A rate-_ 2 t consuumption of A | Volume in ml Time required for Volume in ml distilled waterconsuming A in seconds Volume in ml.

Explanation / Answer

Volume of solution A in mL = 10 mL

Molarity of the solution = 0.0080M

Final Volume of Solution = 10 mL + 10 mL + 30 mL = 50 mL

The number of moles will remain the same

M1V1 = M2V2

(0.0080)(10) = (M2)(50)

M2 = 0.0016M

Hence the correct answer is Option C
