The rate law for a reaction between substance P \& Q is given by
Rate = k[P]^x [Q]^y
If concentration of P is doubled and concentration of Q is halved, the ratio of the new rate to the earlier rate of reaction will be : 

Identify the product ' \(X\) ' and ' \(Y\) ' in the following reaction.

Answer the question on basis of passage given below :
Adsorption is surface phenomenon and it differs from absorption which occurs throughout the body of the substance which absorbs. In physisorption the attractive forces are mainly van der Waal forces while in chemisorption actual bonding occurs between the particles of adsorbent and adsorbed more easily on the surface of a solid as compared to the gases which are liquified with difficulty. Adsorption increases with the increases in pressure and decreases as temperature is increased.
The ease with which the gases \(H _2, CH _4, CO _2 \backslash \& NH _3\) are adsorbed on the surface of charcoal is -

Which of the following are the properties of Normal Distribution function f(x) and Normal probability curve:
(A) The probability of success remains the same in each trial and the number of trials is small in number.
(B) The curve is bell shaped and is symmetrical about the mean.
(C) If set of n trials are repeated N times, then frequency f(r) of r successes is given by
f(r) = N.P(r) = \(N e^{-m} \frac{m^r}{r!}\), r = 0, 1, 2...
(D) As x increases numerically, f(x) decreases rapidly and the maximum value of f(x) occurs at x = μ(mean).
