Question

The rate of reaction between 0.1 M Na2S2O3, and 1M HCI does NOT depends on
A.temperature
B.concentration
C. pressure
D. catalyst
​

Answer 1

Answer:

d number is the answer of this question

Answer 2

Answer:

The rate of reaction between 0.1 M Na₂S₂O₃, and 1M HCI does NOT depend on pressure.

Explanation:

The products of the reaction between 0.1 M Na₂S₂O₃, and 1M HCI are sulphur dioxide, water, sodium chloride and a sulphur atom.

Na₂S₂O₃ + 2HCI → H₂O + SO₂ + 2NaCl + S

• The rate of a reaction is significantly affected by a change in temperature. For most of the chemical reactions, the rate increases with an increase in the temperature. The rate usually becomes double for every 10° rise in temperature.

The rate of precipitation of sulphur increases by increasing the temperature.

• The rate of a chemical reaction refers to the speed with which the reactants change into products. It is expressed in terms of a decrease in the concentration of any of the reactants per unit time or an increase in the concentration of any of the products per unit time.

On increasing the concentration, the molecular collision increases, which increases the chances of product formation.

• A catalyst is a substance which alters the rate of the reaction without being used up in the reaction. It can increase as well as decrease the rate of a reaction.

Thus, the rate of a reaction depends on temperature, concentration and presence of a catalyst.
