Free energies of formation `(Delta_(f)G)` of MgO(s) and Co(g) at 1273 K and 2273 K are given below : `Delta_(f)G^(@) (MgO(s))=-941 kJ//"mol at" 1273 K` `Delta_(f)G^(@) (MgO(s))=-344 kJ//"mol at" 2273 K` `Delta_(f)G^(@) (CO (g)) =- 439 kJ//"mol at" 1273 K` `Delta_(f)G^(@) (CO(g))=-628 kJ//"mol at" 2273 K` On the basis of the above data, predict the temperature at which carbon can be used as reducing agent for MgO(s). |
|
Answer» The redox reaction for MgO (s) is : `MgO(s) +C(s) to Mg(s) +CO(g)` In order that it may proceed, `DeltaG^(@)` must be negative. According to Gibbs Helmholtz equation. `DeltaG^(@)=Delta_(f)G^(@)("products")-Delta_(f)G^(@) ("reactants")` At 1273 K, `DeltaG^(@)=Delta_(f)G^(@)CO(g)-Delta_(f)G^(@)MgO (s)` `=(-439)-(-941)=502 " kJ mol"^(-1)` The reaction will not be feasible as `DeltaG^(@)` is positive. At 2273 K , `DeltaG^(@)=Delta_(f)G^(@)CO(g)-Delta_(f)G^(@)MgO(s)` `=(-628)-(-344)=-284 " kJ mol"^(-1)` The reaction is feasible which means that MgO can be reduced by coke at 2273 K. |

|
Answer» Mutual Funds do not provide assured returns. Their returns are linked to their performance. They invest in shares, debentures, bonds etc. All these investments involve an element of risk. Some of the Risk to which Mutual Funds are exposed to is given below: Market risk: If the overall stock or bond markets fall on account of overall economic factors, the value of stock or bond holdings in the fund’s portfolio can drop, thereby impacting the fund performance Non-market risk: Bad news about an individual company can pull down its stock price, which can negatively affect fund holdings Interest rate risk: Bond prices and interest rates move in opposite directions. When interest rates rise, bond prices fall and this decline in underlying securities affects the fund negatively. Credit risk: Bonds are debt obligations. So when the funds invest in corporate bonds, they run the risk of the corporate defaulting on their interest and principal payment obligations. |
