Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature in the room where the reaction takes place. This can make the room feel cooler as the reaction uses up the heat energy present in the environment.
An endothermic reaction can be spontaneous at room temperature if the increase in entropy of the system is large enough to overcome the energy input required for the reaction. This can happen if the products of the reaction have higher entropy than the reactants. As a result, the overall change in free energy can be negative even though the reaction is endothermic.
An increase in room temperature would not necessarily increase the rate of reaction. While it can often increase reaction rates due to the increased kinetic energy of molecules, there are instances where the reaction might not be temperature-sensitive. The other factors listed—reactants being more concentrated, presence of a catalyst, and presence of an enzyme—will typically increase the rate of a reaction.
Mixing cold vinegar with baking soda will result in a smaller reaction compared to using room temperature vinegar. This is because the reaction between baking soda and vinegar is exothermic, meaning it produces heat. Warmer vinegar provides more energy for the reaction, leading to a more vigorous fizzing reaction.
Calcium (Ca) does react with water at room temperature, although the reaction is not as vigorous as that of more reactive alkali metals. When calcium is added to water, it forms calcium hydroxide and hydrogen gas. The reaction can produce bubbles of hydrogen, which can ignite if the heat generated is sufficient. Overall, while the reaction occurs, it is relatively mild compared to other metals in the same group.
It is an oxidation reaction.
Carbon, nitrogen, and sulfur all form oxides which are gaseous at room temperature.
How does temperature affect the reaction of Sodium Bicarbonate synthesis?
At room temperature, any reaction.

yes
For the reaction to occur at room temperature, an external energy source must be provided to drive the reaction, and the reaction will absorb heat from the surroundings. The reaction is non-spontaneous because it does not occur naturally without intervention.
This reaction is possible also at low temperature.
Electrolysis typically occurs at room temperature, as it is a process that involves the use of an electric current to drive a non-spontaneous chemical reaction. However, the rate of electrolysis may be influenced by temperature, as higher temperatures can increase reaction rates.
Methane and oxygen do react with each other at room temperature, but the reaction requires an input of energy to get started. Once the reaction begins, it is exothermic and produces heat and water as byproducts. This reaction typically needs a spark or flame to initiate it, which is why methane does not spontaneously combust in air at room temperature.
