A complex reaction involving two series reactions can be of the type, A reacts to give B, which is then transformed to C. Both the elementary reactions (1) and (2) exhibit first - order kinetics, that is, For this reaction, [A] = [A] o exp (-k 1 t) (36) It is difficult to derive the conce..

Summary - (i) Let X be a set of numbers and f : N n X be a function, then the ordered set {f(1), f(2),...., f(n)} is called a finite sequence in X. (ii) Let X be a set of numbers and f : N X be a function, then the ordered set {f(1), f(2),....} is called an infinite sequence in X. If {T n } is a se..

The sum of an infinite geometric series is 12 times the first term. What is its common ratio? => 12 11 or 1 12 or 1 11 or 11 12..

The time series graph represents Carol's annual income. Find the average monthly income in the year 1995. => $90,000 or $7,500 or $90 or $7.5..

In an electrical circuit, energy is supplied by the source of EMF, stored by the capacitive and inductive elements and dissipated in resistive elements. Conservation of energy requires that, at any particular time, the rate at which energy is supplied by the source of EMF must equal the r..
