Answer to Question #347004 in Chemistry for king

Question

A. One mole each of compounds A and B reacts to give one mole each of products C and D, at 25 oC. The reaction is first-order with respect to A and first order overall.

i. What is the order with respect to reactant B?

ii. How will the rate of the reaction change when B’s concentration is doubled?

iii. Write the rate law for this reaction.

iv. Explain if this rate law is consistent with the reaction stated.

v. Define the term ‘half-life of a reactant’.

vi. Calculate the half-life of reactant A at 25 oC if the rate constant (k) at this temperature is 0.052 s-1 .

B. Explain how:

i. the rate of a chemical reaction can be determined graphically.

ii. a catalyst affects the rate of a chemical reaction.

iii. the surface area of reacting particles impact reaction rates.
