Some advantages
<span><span>Produce relatively low amounts of carbon dioxide (CO2).</span>Well-developed engineering knowledge. Single plant can generate high amount of power.</span>
Some disadvantages
<span>Radioactive waste, an extremely dangerous byproduct, needs careful monitoring for thousands of years. Accidents may create havoc on a large scale.<span>Uranium, the primary energy source, is estimated to be available only for the next 30 to 60 years without the use of high-efficiency breeder reactors.</span></span>
The right answer is the activation energy.
The catalyst increases the reaction rate by introducing new reaction paths (mechanism), and lowering its activation energy, or activation Gibbs free energy. By doing this it can increase the speed, or lower the temperature of the reaction. It is important to note that the catalyst does not alter the total Gibbs free energy of the reaction which is a system state function and therefore has no effect on the equilibrium constant.
