The following reaction is performed at 298 K. $2NO(g)+O_{2}(g)⇔2NO_{2}(g)$ The standard free energy of formation of $NO(g)$ is 86.6 kJ/mol at 298 K. What is the standard free energy of formation of $NO_{2}(g)$ at 298 K ? $(K_{P}=1.6×10_{12})$

Consider an ideal gas confined in an isolated closed chamber. As the gas undergoes an adiabatic expansion the average time of collision between molecules increases as $V_{q}$, where V is the volume of the gas. The value of q is : $(γ=C_{v}C_{p} )$

If $[a×bb×cc×a]=λ[abc]_{2}$, then l is equal to

The sum of first 9 terms of the series $11_{3} +1+31_{3}+2_{3} +1+2+31_{3}+2_{3}+3_{3} +.....$is

Two short bar magnets of length 1 cm each have magnetic moments $1.20Am_{2}and1.00Am_{2}$ respectively. They are placed on a horizontal table parallel to each other with their N poles pointing towards the South. They have a common magnetic equator and are separated by a distance of 20.0 cm. The value of the resultant horizontal magnetic induction at the mid - point O of the line joining their centres is close to (Horizontal component of earths magnetic induction is $3.6×10_{−5}Wb/m_{2})$

If all the words (with or without meaning) having five letters, formed using the letters of the word SMALL and arranged as in a dictionary; then the position of the word SMALL is :
