Answer:- It is choice D.
Explanations:- In general, a neutralization reaction is the reaction of an acid with base to form salt and water.
in first reaction the reaction is taking place between ammonia(a base) and hydrochloric acid(an acid) to form their salt(ammonium chloride). So, it is an acid-base neutralization reaction.
In second reaction, sodium hydroxide(a base) is reacting with acetic acid(an acid) to form their salt(sodium acetate) and water. So, it is an acid-base neutralization reaction.
In third reaction, Nitric acid is reacting with calcium hydroxide(a base) to form a salt(calcium nitrate) and water. So, it is an acid-base neutralization reaction.
In fourth reaction, sulfuruc acid is reacting a sodium chloride(a salt) to give a double replacement reaction. It is not an acid-base neutralization reaction as it's not taking place between an acid and base.
So, the correct choice is D.
The Arrhenius equation describes the relation between the rate of reaction and temperature for many physical and chemical reactions
It is an expression that provides a relationship between the rate constant (of a chemical reaction), the absolute temperature.
The Arrhenius equation,
k = , where
k is the rate constant,
z is the collision factor,
p is the steric factor,
Ea is the activation energy,
R = 8.3245 is the ideal gas constant, and,
T is the temperature.
The activation energy by definition, is the minimum energy (or threshold energy) required for two particles of reactants upon collision to form products.
The Arrhenius equation could also be written as:
⇒ k = , where
⇒ A = zp, the Arrhenius factor.
Taking the neutral logarithm of both parties, we get:
⇒ In k = + In A,
Assuming that, A is independent of temperature, when T is increased, the equilibrium constant k will also increase and therefore, the rate of the reaction will also increase.
