Q14:What is the effect of catalyst on: (i) Gibbs energy (ΔG) and (ii) activation energy of a reaction? Answer: (i) The catalyst will have no influence on Gibb’s energy. (ii) By lowering the activation energy of a process, the catalyst gives an alternate pathway. ...
The activation energy of a reaction can be determined by View Solution State the underlying princeiple of mater bridge. Draw the circuit diagram and explain how the unknown resistance of a conductor can be determined by this method. View Solution The order of reaction is determined by stoichiome...
In this paper, the Arrhenius' cquation and activation energy were discussed.The author introduced the concept of activation energy of reactant molecule and indicated that the activation energy of reactant molecule is different from the activation energy of reaction. The difference of this two concept...
