Which of the following changes would increase the rate of a reaction between vinegar and sodium hydroxide? (2 points) question 21 options: 1) heating up the vinegar 2) diluting the vinegar 3) cooling the sodium hydroxide 4) decreasing the volume of the container save

The correct answer is Option 1.

Explanation:

Rate of reaction can be increased by the following factors:

1. Concentration of the reactants: Greater the concentration of the reactants, faster is the reaction. Conversely, as the concentration of the reactants decrease, the rate of reaction also decreases.

2. Temperature: The rate of the reaction increases with increase in temperature.

3. Surface area of the reactants: For the reaction involving a solid reactant, the smaller is the particle size that is the greater is the surface area, faster will be the reaction.

From the given options, Temperature is playing the role in increasing the rate of the reaction.

Heating of vinegar will lead to the increase in the rate of the reaction because temperature is also increasing.

Hence, the correct answer is Option 1.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
