The curve showing variation of x/m with temperature is inverted 'V' shape. What is the type of adsorption ?

The following are some statements about adsorption of solutes from the solutions. A) Increase in the surface area of the adsorbent increases the extent of adsorption. B) Increase in temperature decreases the extent of adsorption. C) The extent of adsorption (x/m) is related to the molar concentration of solution ( c) is given by x//m = k.c^(1//n) The correct combination is

Variation of volume with temperature was first studied by French chemist, Jacques Charles, in 1787 and then extended by another French chemist Joseph Gay-Lussac in 1802. For a fixed mass of a gas under isobaric condition, variation of volume V with temperature t°C is given by V = V_(0)[l + alphat] where V_(0) is the volume at 0°C, at constant pressure. 1 or every 1° change in temperature, the volume of the gas changes by............... of the volume at 0^(@) C

Sachin recorded the temperature as -12^@C instead of +12^@C . what is the variation of the temperature?

When pH or temperature is plotted against enzyme activity the shape of curve obtained is
