Q1
In a reaction A → B, if the rate of formation of B is 0.1 mol/L·s, what is the rate of disappearance of A?
0.1 mol/L·s
0.05 mol/L·s
0.2 mol/L·s
0.1 L/mol·s
For the reaction A → B, the rate of disappearance of A is equal to the rate of formation of B, hence it is 0.1 mol/L·s. However, if stoichiometry is considered as 1:1, the rate of disappearance of A is also 0.1 mol/L·s.

Q
Q: In a reaction A → B, if the rate of formation of B is 0.1 mol/L·s, what is the rate of disappearance of A?
Solution: For the reaction A → B, the rate of disappearance of A is equal to the rate of formation of B, hence it is 0.1 mol/L·s. However, if stoichiometry is considered as 1:1, the rate of disappearance of A is also 0.1 mol/L·s.
Steps: 6
Step 1: Identify the reaction. We have a reaction where A turns into B, written as A → B.
Step 2: Understand what 'rate of formation of B' means. It tells us how fast B is being produced in the reaction.
Step 3: Note the given rate of formation of B, which is 0.1 mol/L·s.
Step 4: Recognize that in a simple reaction like A → B, the rate of disappearance of A is related to the rate of formation of B.
Step 5: Since the reaction is a 1:1 conversion (1 mole of A makes 1 mole of B), the rate of disappearance of A is the same as the rate of formation of B.
Step 6: Therefore, the rate of disappearance of A is also 0.1 mol/L·s.
