The reaction, Cr_(2)O_(3(s)) + 2Al_((s)) rarr Al_(2)O_(3) + 2Cr Delta G^(@) = -421 kJis thermodynamically feasible why does it not take place at room temperature? |
| Answer» Solution :The CHANGE in Gibbs energy is related to the equilibrium constant K as `DeltaG = -RT` Ink. At room temperature allreactants and PRODUCTS of the given REACTION are in solid state. As a result, equilibrium does not take place at room exist between the reactants and the products. Hence the reaction does not take place at room temperature. Certain amount of activation energy is essential even for reactions which are thermodynamically feasible. | |
