When the change in concentration is 6 x 10-4 mol dm-3 and time for that change is 10 seconds, the rate of reaction will be:
- A
6 × 10-3mol dm-3 sec-1
- B
6 × 10-4 mol dm-3 sec-1
- C
6 × 10-2 mol dm-3 sec-1
- D
6 × 10-5 mol dm-3 sec-1
𝑟𝑎𝑡𝑒 𝑜𝑓 𝑟𝑒𝑎𝑐𝑡𝑖𝑜𝑛 = Δ𝐶/𝑡 = (6 × 10−4 )/10 = 6 × 10−5𝑚𝑜𝑙𝑑𝑚−3𝑠𝑒𝑐−1
Given: Change in concentration = 6 x 10^(-4) mol dm^(-3) Time = 10 seconds
Rate of reaction = Change in concentration / Time
Substituting the given values:
Rate of reaction = (6 x 10^(-4) mol dm^(-3)) / 10 seconds
Simplifying:
Rate of reaction = 6 x 10^(-5) mol dm^(-3) sec^(-1)
Among the given options, the closest value to the calculated rate is Option D: 6 x 10^(-5) mol dm^(-3)
sec^(-1).
Therefore, the rate of reaction will be approximately 6 x 10^(-5) mol dm^(-3) sec^(-1).
This option is incorrect as per explantion and calculations.
