that experimentation

The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case of gas phase reactions), pH, optical rotation, electrical c..

Consider a spherical vessel having four cylindrical tubes A, B, C and D, each fitted with airtight frictionless piston, of area of cross-section 4a, 3a, 2a and a, respectively. When the vessel is filled with an incompressible liquid so that no air gap is left inside the vessel, a force 4 ..

Travel in Straight LinesWhen an opaque object like a metal cross is placed in the path of cathode rays in a discharge tube, a shadow of the metal cross is formed at the end opposite to the cathode. The placement of the shadow proved that these rays follow a straight line. Produce Mechanical..
