Equal amount of a reactant were taken in two closed flasks of same capacity but even then the rate of reaction in one flask was found to be higher than the other. Under what conditions it is possible?

Two moles of N_2 and two moles of H_2 are taken in a closed vessel of 5 litres capacity and suitable conditions are provided for the reaction. When the equilibrium is reached ,it is found that a half mole of N_2 is used up. The equilibrium concentration of NH_3 is

A ray of light travelling with a speed c leaves point 1 shown in figure and is reflected to point 2. The ray strikes the reflecting surface at a distance x from point 1. According to Fermat's principle of least time, among all possible paths between two points , the one actually taken by a ray of light is that for which the time taken is the least (In fact there are some cases in which the time taken by a ray is maximum rather than a minimum). Under what condition is time taken least?

The resistance of two electrolytes X and Y ere found to be 45 and 100 respectively when equal volumes of both the solutions were taken in the same cell in two different experiments. If equal volumes of these solutions are mixed in the same cell, what will be the conductance of the mixture?

Two moles of each reactant A and B are taken in a reaction flask. They react in the following manner, A(g)+B(g)hArr C(g)+D(g) At equilibrium, it was found that the concentration of C is triple to that of B the equilibrium constant for the reaction is

In Haber process 30 litre of dihydrogen and 30 litres of dinitrogen were taken for reaction which yielded only 50% of the expected product. What will be the composition of gaseous mixture under the aforesaid condition in the end ?

There are two closed containers A and B. Container A contains PCl_5 gas at 25^@C temperature and 1 bar pressure. Container B contains equilibrium mixture of gases obtained by partial decomposition of PCl_(5) (g) at the same temperature and pressure. Assuming that initially equal mole of PCl_(5) (g) at same temperature and pressure . Assuming that initially equal moles of PCl_(5) were taken into the containers ( before decomposition ), the gases are allowed to effuse through a pinhole in the containers, Which container will show higher rate of effusion ? Justify .

Wind is blowing west to east along twoparallelracs. Two trais moving with the same speed in opposite directions on these tracks have the steam tracks. If one stream track isdouble than the other, what is the speed of each train ?

The rate law expresison is given for a typical reaction, n_(1)A + n_(2) B rarrP as r = k[A]^(n)[B]^(n2) . The reaction completes only in one step and A and B are present in the solution. If the reaction occurs in more than one step, then the rate law is expressed by consdering the slowest step, i.e., for S_(N)l reaction r = k[RX] . If the eraction occurs in more than one step and the rates of the steps involved are comparable, then steady state approximation is conisdered, i.e., the rate of formation of intermediate is always equal to the rate of decompoistion of the intermediate. Conisder the reaction: [[I_(2) underset(k_(1))overset(k_(2))hArr2I("rapid equilibrium")],[H_(2)+2I overset(k_(3))rarr 2HI("slow")]] If we increase the concentration of I_(2) two times, then the rate of formation of HI will

Two wires of equal cross section but one made of steel and the other of copper, are joined end to end. When the combination is kept under tension, the elongations in the two wires are found to be equal. Find the ratio of the lengths of the two wires. Young modulus of steel =2.0xx10^11Nm^-2 and that of copper =1.1xx10^11Nm^-2

Which of the following should be chosen for best yield if one were to produce a recmobinant protein in large amounts ? (a) Laboratory flask of largest capacity (b) A stirred-tank bioreactor without in-lets and out-lets (c) A continuous culture system (d) Any of the above
