A chemical reaction prouces 5.1 g of a product in 3.1 seconds. what is the average reaction rate ? (2 marks).
Answers
Answer:
Plan The average rate is given by the change in concentration, ∆[A], divided by the change in time, ∆t. Because A is a reactant, a minus sign is used in the calculation to make the rate a positive quantity.
The average rate of reaction is 1.6g/s.
Given,
A chemical reaction produces 5.1 g of a product in 3.1 seconds.
M = 5.1 g
S = 3.1 seconds.
To Find,
The average rate of reaction.
Solution,
Let's understand the concept of the average rate of reaction and its formula.
Average Rate of Reaction (A):-
The average rate is calculated by dividing the increase in concentration by the increase in time. In order to make the rate positive, a minus sign is used for A, which is a reactant.
Formula:
The average rate of reaction = Product Produced / Time
Let's solve the question using the above formula.
A =?
M = 5.1g
T = 3.1 s
A = 5.1/3,1
On solving, we get,
A = 1.61 g/s
The average rate of reaction is 1.6g/s.
