Consider the reaction
Suppose that at a particular moment during the reaction molecular hydrogen is reacting at the rate of 0.074 M/s. (a) At what rate is ammonia being formed? (b) At what rate is molecular nitrogen reacting?
(a)

Interpretation:
The rate at which
Concept introduction:
Rate: The rate is nothing but the change in concentration of substrate (reactant) or target (product) with time.
- The change in concentration term is divided by the respective stoichiometric coefficient.
- The negative sign indicates that substrates (reactants) concentration decrease as per the reaction progress.
- Rate of reaction is always represented by positive quantities.
Rate of the reaction is the change in the concentration of reactant or a product with time.
For a general reaction,
The negative sign indicates the reduction of concentration of reactant.
Answer to Problem 13.8QP
The rate at which
Explanation of Solution
The given reaction is,
We have to calculate the rate of ammonia in the above reaction is as follows
(b)

Interpretation:
The rate at which molecular nitrogen reacts in the given reaction has to be determined from the given information.
