Define the following: (i) Elementary step in a reaction (ii) Rate of a reaction

Entropy is zero only at absolute zero. Enthalpy of formation is the heat change involved in the formation of one mole of the substance from its elements. An element formed...

No, an elementary process would have a rate law with orders equal to its molecularities and therefore must be in integral form.

The answer is.... Zero order

A reaction which takes place in one step is called an elementary reaction. For example : H2 + I2 => 2HI. 

3.6 x 10-3 Ms-1 , 5.4 x 10-3 Ms-1

No, an elementary process would have a rate law with orders equal to its molecularities and therefore must be in integral form.

A reaction which takes place in one step is called an elementary reaction. For example : H2 + I2 => 2HI.

An experimentally determined expression which relates the rate of reaction with the concentration of reactants is called rate law while the rate of reaction when concentration of each reactant is...

Working of a transformer is based on the principle of mutual induction. Transformer cannot step up or step down a dc voltage.  Reason: No change in magnetic flux.  Explanation: When dc voltage...
