7-10 The rate of disappearance of HCI was measured for the following reaction:
The initial concentration of HCI is 1.85 M. Its concentration decreases to 1.58 M in 54.0 min. What is the

Concept introduction:
Rate of reaction: The rate of the reaction is defined as extent of a reaction. For any reaction, it depends on the concentration change of limiting reagent formed in a reaction.
Concentration: Concentration of all chemical species takes part in a reaction depend on their moles present in per liter solution.
The rate is change in concentration of the reactant with change in time. It is mathematically represented as follows:
Answer to Problem 7.10P
Rate of reaction = 0.005 M/min
Explanation of Solution

Reaction with initial concentration of
Put the given values in above expression.
Here, negative sign indicates the concentration of HCl decreases.

- The label on a bottle of 3% (by volume) hydrogen peroxide, H2O2, purchased at a grocery store, states that the solution should be stored in a cool, dark place. H2O2decomposes slowly over time, and the rate of decomposition increases with an increase in temperature and in the presence of light. However, the rate of decomposition increases dramatically if a small amount of powdered MnO- is added to the solution. The decomposition products are H2O and O2. MnO2 is not consumed in the reaction. Write the equation for the decomposition of H2O2. What role does MnO2 play? In the chemistry lab, a student substituted a chunk of MnO2 for the powdered compound. The reaction rate was not appreciably increased. WTiat is one possible explanation for this observation?
