Rate = k[NO]^(2) [O_(2)]^(1) . By how many times does the rate of reaction change when the volume of the reaction vessel is reduced to 1//3^(rd) of its original volume ? Will ther he any change in the order of the reaction.

Logistic growth model is more realistic than exponential growth model. Why?

Comprehension The first demonstration of the stereochemistry of the S_(N^2) reaction was carried out in 1934 by Prof. E.D Hughes and his colleagues at the University of London. They allowed (R) -2- iodooctane to react with radioactive iodide ion (""^(**)I-) The rate of substitution (rate constant K_5 ) was determined by measuring the rate of incorporation of radioactivity into the alkyl halide. The rate of loss of optical acitivity from the alkyl halide (rate constant K_0 ) was also determined under the same conditions: What ratio K_0//K_s is predicted for each of the following stereochemical scenarios : For equal amounts of both retention and inversion ?

If in a population of size N, the birth rates represented as b and death rates as d,then derive the formula to calculate the increase or decrease in N during a unit time period t (dN/dt).
