Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
The equilibrium is shifted to the endothermic side, so heat is absorbed.
More reactants form- Nova net

Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
Increasing the temperature generally increases the speed with which molecules move.
All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate
Raising the temperature makes chemical reactions faster.
a} Is very high.
No that is false. Increasing temperature favors the reaction that absorbs energy, not that releases energy as heat.
As the temperature increases, the reaction time decreases.
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
Many reactions are of the form:dCA/dt = kCAdCA/dt is the change in concentration of A with timek is the reaction rate constantCA is the concentration of AThe rate constant often exhibits an Arrhenius relationship, so:k=Ae^(-Ea/RT)A is a pre-exponential term (constant)Ea is the activation energy of the reaction (constant)R is the universal gas constant (constant)T is the temperature of the reactionTherefore, as T increases, the value of the exponential term increases. This means that k will increase as T increases, and therefore dCA/dt will increases as T increases.Hope that helps!
yes, as the reaction rate increases with increase in the temperature
The maximum temperature is attained when the reaction is completed.
Increasing the temperature generally increases the speed with which molecules move.
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
The temperature of the system
All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate
It increases the collisions that result in a reaction. or it increases the kinetic energy of the molecules.
