In BOF, desiliconisation is a first order reaction. So the silicon content of the metal decreases
For the reaction, A = X + Y, the respective concentrations are CA, CX and CY. The forward reaction rate constant is kf and the backward reaction rate constant is kb. Choose the correct statement from the following:
P. At equilibrium, kf CA > kB CxCy
Q. If the reaction is irreversible than, kb CXCY = 0
R. The backward reaction rate will essentially be first order, if the forward reaction rate is first order.
S. Activation energy for the first order forward reaction will be independent of temperature.
Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is

In the consumable electrode shielded metal arc welding process, which of the following observations are correct?
P. The, weld composition does not depend upon the basicity of the slag.
Q. Basic flux is used to achieve low hydrogen content-and low inclusion content in the weld metal.
R. Reverse polarity of the direct current power source is used to weld thin sheets.
S. Coated electrodes are classified by tensile strength of the weld metal deposit.
