A thermonuclear fusion reactor is better than a fission reactor for all of the following reasons, except that
  • a)
    for the same mass of substances involved, a fusion reaction releases much more energy than a fission reaction
  • b)
    a fusion reaction can be much more easily controlled than a fission reaction
  • c)
    a fusion reaction produces almost no radioactive waste
  • d)
    the fuel required for fusion is readily available in abundance from seawater
Correct answer is option 'B'. Can you explain this answer?

A thermonuclear fusion reactor is better than a fission reactor for a...
Thermonuclear reaction is difficult to produce in a controlled manner because we have to provide enough energy to overcome the force of repulsion between reacting particles before fusion can occur or we can say to produce a self-sustaining reaction, we have to provide the particles with enough thermal energy so that they can fuse when they collide.
Each fusion reaction is characterized by a specific ignition temperature, which must be surpassed before the reaction can occur. The deuterium and tritium reaction has an ignition temperature above 108 K. In a hydrogen bomb, a fission reaction produced by a small atomic bomb is used to heat the contents to the temperature required to initiate fusion. Hence we can say that it is very difficult to control a nuclear fusion reaction.

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: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
