Question

HCL + NaOH → H2 + NaCl
In which of these would the reaction rate be the quickest?

A) A 1M HCl solution reacts with a 1M NaOH solution
B) A 1M HCl solution reacts with a 2M NaOH solution
C) A 2M HCl solution reacts with a 1M NaOH solution
D) A 2M HCl solution reacts with a 2M NaOH solution

Answer 1

The answer is D
 "A 2M HCl solution reacts with a 2M NaOH solution".

Answer 2

Answer:

D) A 2M HCl solution reacts with a 2M NaOH solution

Explanation:

The rate of a reaction increases with the increase in concentration of the reactants. For a reaction to occur there must be effective collision. Effective collision increases when there is a high concentration of the reactants. Also the reactants must be oriented in the right direction for the effective collision to take place,
