A gas bubble from an explosion under water, oscillates with a period T proportional to`p^ad^bE^c`where P is the static pressure, d density of water, E total energy of explosion. Find value of a, b c.

In the reversible gaseous reaction , A + 2B hArr C+3D The partial pressure of A B C and D are 0.20 , 0.10 , 0.30 ,0.50 atm respectively at equilibrium. The numerical value of K_p is :

What do you mean by elevation in boiling point and molal elevation constant ? B.P of water at 750 mm Hg is 99.63^@C . How much sucrose is to be added to 500 g of water such that it boils at 100^@C ? Molal elevation constant of water is 0.52 K kg mol^(-1)

An expression of the form (a+b+c+d+ .... ) consisting of sum of many distinct symbols is called a multinomial. Show that (a+b+c)^n is the sum of all terms of the form n!/p!q!e!a^pb^qc^r where p, q and r range over all possible triples of non negative integers such that p+q+r = n.

For a reaction 2A + B ⇌ C + D , the partial pressure of A, B, C and D at equiliberium are 0.5, 0.8 0.7 and 1.2 atmosphere respectively. The value of k_p for this reaction is :

At 40^@C, the vapour pressures (in torr) of methyl alcohol (A) and ethyl alcohol (B) solution is represented by: P=120X_A + 138, where X_A is mole-fraction of methyl alcohol, then the value of lim X_A rarr 0 P_B^@/X_B and lim X_B rarr 0 P_A^@/X_A are:
