Answer:
Shift it to the left toward the reactants.
Explanation:
Le Chatelier's principle states that if a chemical system is in equilibrium and one of the factors involved in the equilibrium is altered (e.g temperature,pressure or concentration) ,the equilibrium will shift, so as to neutralize the effect of the change.
If a chemical system is in equilibrium, in which the reaction is exothermic and the temperature is being increased, the equilibrium will shift to left, favoring the backward reaction (reactants) as the constant K decreases.
The answer is: To have easy access to a coolant for the reactor.
Hope this helps!:)

Answer:
α = 1.114 × 10⁻³ (°C)⁻¹
Explanation:
Given that:
Length of rod (L) = 1.5 m,
Diameter (d) = 0.55 cm,
Area (A) =
Radius (r) = d / 2 = 0.275 cm,
Voltage across the rod (V) = 15.0 V.
At initial temperature (T₀) = 20°C, the current (I₀) = 18.8 A while at a temperature (T) = 92⁰C, the current (I) = 17.4 A
a) The resistance of the rod (R) is given as:
Therefore the resistivity and for the material of the rod at 20 °C (ρ) is:
b) The temperature coefficient of resistivity at 20°C for the material of the rod (α) can be gotten from the equation:
Rearranging to make α the subject of formula:
