Question

Drug B and C undergoes degradation reaction in solution. Investigation of this reaction led to the availability of [B] and [C] versus time data, which is represented in the table shown below. Please use this information in answering the various parts of this problem

The kinetic order for the decomposition of the drug B and C over the course investigated will be

a. First order for B and C

b. Zero order for B and C

c. First order for B and zero order for C

d. Zero order for B and first order for C

The half life of B degradation is about

a. 2.24 hr

b. 2.5 hr

c. 3 hr

d. 10 hr

The half life of C degradation is about

a. 10 hr

b. 1 hr

c. 5 hr

d. 7 hr

I need help with these 3 questions!!, show work and which letters are the correct answers!?

Explanation / Answer

Answer : A} it is varied via a time means the rate of the reaction is only depends upon the time and hence it is a first order reaction . option [a ] is correct .

B ] initially the B is present around 10mM and finally it is left 1.42 means 8.58 mM is decomposed and in haLF LIFE IT is decompose 4.29 mM which takes time 2.24hr means option A is correct .

C] half life of C is also it is decomposes 6 mM and in half life it decomposes 3mM which take times around 3hr.
