Which of the following reaction is possible at anode :- (1) F2 2e- --...
Explanation of Possible Reactions at Anode
- 1. F2 2e- --> 2F-
This reaction is possible at the anode as fluorine gas is being oxidized to fluoride ions by losing electrons. This is a typical oxidation reaction that occurs at the anode during electrolysis.
- 2. 2H 1/2 O2 2e- --> H2O
This reaction is not possible at the anode as hydrogen gas is being reduced to form water by gaining electrons. Anode reactions involve oxidation, not reduction.
- 3. 2Cr2^3 7H20 --> Cr2O7^2- 14H 6e-
This reaction is possible at the anode as chromium ions are being oxidized to form dichromate ions by losing electrons. This is a typical oxidation reaction that occurs at the anode during electrolysis.
- 4. Fe^2 --> Fe^3 e-
This reaction is not possible at the anode as iron ions are being reduced to form iron ions with a higher charge by gaining electrons. Anode reactions involve oxidation, not reduction.
In conclusion, reactions 1 and 3 are possible at the anode as they involve oxidation reactions, while reactions 2 and 4 are not possible as they involve reduction reactions. Anode reactions involve the loss of electrons, leading to the oxidation of species.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Reactions can occur at different speeds.Reason: Rate of reaction is also called speed of reaction.
