Depression in Freezing Point

Rate constant...

Question

Rate constant of a reaction is 0.0693 min^-1,starting with 10 moles. Rate of reaction after 10 minutes is ???

Open in App

Solution

0.3465 mol/ min

Rate of reaction = k × concentration at time t

Here concentration after t1/2 = 5 moles

(That is 50% of 10 moles)
T1/2 is the time for completion of 50% reaction
