Question

drive zero order reaction and first order reaction​

Answer 1

Answer:

If the number of enzyme molecules is limited in relation to substrate molecules, then the reaction may appear to be zero-order. If B is present in great excess, then the reaction will appear to be zero order in B (and first order overall). This commonly happens when B is also the solvent that the reaction occurs in.

Answer 2

Answer:

Consider a zero order reaction

R→P

Rate =dt−d[R]=k[R]o

dt−d[R]=k[R]o

dt−d[R]=k

d[R]=−k⋅dt

Integrating on both sides

[R]=−kt+I  (1)

k=t[R]o−[R]
