Q
Q: For a zero-order reaction, if the initial concentration is 0.5 M and the rate constant is 0.1 M/s, how long will it take to reach 0 M? (2019)
Solution:
For a zero-order reaction, t = [A₀] / k. Here, t = 0.5 M / 0.1 M/s = 5 s.
Steps: 6
Show Steps
Step 1: Identify the initial concentration of the reactant, which is given as 0.5 M.
Step 2: Identify the rate constant, which is given as 0.1 M/s.
Step 3: Use the formula for a zero-order reaction, which is t = [A₀] / k.
Step 4: Substitute the values into the formula: t = 0.5 M / 0.1 M/s.
Step 5: Perform the division: 0.5 M divided by 0.1 M/s equals 5 seconds.
Step 6: Conclude that it will take 5 seconds to reach 0 M.
