there is no end-scale "highest" temperature, to put this in easy terms : the bigger the bang the higher the temperature, to answer the Question: the highest temperature would probably be the temperature created when the big-bang occurred.
If you meant to say 'very high' temperature, you probably mean nuclear fusion

An increase in temperature speeds up the reaction rate.
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
The most exothermic reaction is nuclear fusion, which is the power of a hydrogen bomb. Nuclear fission is also extremely exothermic.An extremely exothermic chemical (as opposed to nuclear) reaction, although maybe not the most ever, is the so-called thermite reaction. Fe2O3 + 2Al ---> Al2O3 + 2Fe ΔH = -851.5 kJ/mol See the Related Questions and Web Links to the left of this answer for more information.
The sun creates several different kinds of heat. Specifically, the sun gives of ultraviolet radiation, along with electromagnetic radiation. UV rays are the ones responsible for sun burn in humans.
No, its not simple. It requires a sophisticated balance of temperature, pressure, and moderation in order to sustain a critical nuclear fission reaction.
Yes. Very much. That is how we get useful heat to make steam, to turn turbines, to make electricity.
Problem on nuclear fusion is upon confinement of reaction in earth atmosphere. Nuclear fusion required very high temperature to initiate the reaction. Sustaining reaction is not easy. It is likely the earliest nuclear fusion will be available commercially by 2050. It is a little far future for the current energy crisis would reach it peak around 2040.

They are...reactions and can lead to new elements; but the big difference is that a nuclear fusion involve particles from the atomic nucleus and a very great energy is needed.
For nuclear fission reactors there is no critical temperature, though they do have a temperature coefficient which makes the efficiency of the chain reaction vary slightly with temperature. This can be negative or positive, obvously a negative coefficient is preferred and is safer. Nuclear fusion is another matter, and very high temperatures are required in tokamaks to get fusion started
A nuclear power plant uses a slow, controlled nuclear chain reaction to heat water and generate electricity. A nuclear bomb uses a very rapid uncontrolled nuclear chain reaction in order to generate a massive explosion.
Beacause they are very alike & Then They Get Wild
A very high temperature (about 100 million Kelvin) is needed for this nuclear fusion reaction.
Hydrogen undergoes nuclear fusion reaction to form helium in the core of the stars. For this generally a very high temperature ~107 K is required.
In a tokamak device, which is the most promising for developing fusion power on Earth, the ionised plasma of the fuel material must be contained in a ring doughnut shaped compartment at very high temperature, a magnetic field is used to control the plasma to keep in the ring shape wihout ever touching the sides. The magnetic field does not actually control the nuclear reaction which is brought about by the high temperature, but it keeps the reaction steady once it starts (in theory, only very short pulses have been achieved so far).
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
