The activation energy for the reaction in this lab is determined by investigating the effects of temperature on reaction rate. Assuming a negative activation energy, Ea, what effect will increasing the temperature have on the rate constant, k? a. Increasing temperature will decrease the rate constant, k. b. Increasing temperature will not have an effect on the rate constant, k. c. Increasing temperature will increase the rate constant, k.

a. Increasing the temperature would decrease the rate constant, k.

Explanation:

The negative activation energy would result when there is an increase in temperature. The effect of this temperature increment on the rate of reaction is a decrease.

Reactions with a negative activation energy proceed in an environment with no limiting factors. The chances that the molecules can collide with each other is also considerably reduced because they are no longer in the space where a collision can occur. The resultant effect on the rate constant is a decrease.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
