In a forest there are two types of deer, in which one type of deer can run very fast . Whaereas second type of deer can not run as fast as the first one. Lions, tigers hunt der for their food. Imagine which type of deer is going to survive in the ofrest, which type of deer population is going to be eliminated? And why ?

In a forest there are two types of deers, in which one type of deer can run very fast. Where as second type of deer can not run as fast as the first one. Lions, Tigers hunt deers for their food. Imagine which type of deers are going to survive in the forest and which type of deers population is going to be eliminated? And why?

Mechanism of a hypothetical recation X_(2)+Y_(2) to 2XY is given below (i) X_(2) to X+X("fast") (ii) X+Y_(2) hArr XY+Y("Slow") (iii) X+Y to XY("fast") The overall order of the reaction will be

Statement-I: At low temperature, DH is the dominant factor for spontaneity of a reaction. Statement-II: The opposing factor TDS remains very small, at low temperature.

Elementary unimolecular reaction have first order rate laws, elementary bimolecular reaction have second order rate laws. A rate law is often derived from a proposed mechanism by imposiing the steady state approximation by assuming that there in pre equilibrium A proposal mechanism must be constant with the experimental rate law. The decomposition of O_(3) obeys the mechanism given below, Step 1: O_(3)hArrO_(2)+(O)- fast Step 2: O_(3)+(O)toO_(2)+O_(2)- slow H_(2)+Br_(2)to2HBr Mechaism : Br_(2)hArr2Br (fast) H_(2)+brtoHBr+H (slow) H+BrtoHBR (Fast) Order of the reaction is

(A) Spontaneous reaction may be slow or fast. (R ) Spontaneous nature deals with feasibility of the reaction but not rate.

A: Spontaeous reaction may be slow or fast. R: Spontanteous nature deals with feasibility of the reaction but not rate.

For a reaction the following mechanism has been proposed , 2A+BtoD+E A+BtoC+D (slow), A+CtoE (fast) The rate law a expression for the reaction is
