Two reactions have identical value of Ea. Does it the mean that they have same rate constant if run at the same temperature?Illustrate.
An air oven A large tin can is used as an air oven. A hole through the lid fitted with a cork holds a thermo- meter, and the saucer or dish rests on a wire gauze bridge placed
between nitrobenzene and phenol which is more reactive towards chlorine and why? Upon reaction with chlorine what products can be formed from the two reactions.
Q. Illustrate modern atomic model of De Broglie? 1. Electrons inhabit the space surrounding the nucleus and can exist in several discrete principal energy levels each designate
The first ionization potentials for Na, K, and Rb are 5.138, 4.341, and 4.166 eV, respectively. Assume that the energy level of the outer electron can be represented by a hydrogenl
