Why is infinite time required for the completion of an ideal reversible process ?

Is rusting of iron reversible process?

Why is latent peried required?

Write down the conditions of reversibility of a process.

75% of a first order reaction is completed in 30 min. What ts the time required for 93.75% completion of the reaction (in minutes) ?

Show that for any first order reaction, the time required for the completion of 99.9% of the reaction is 10times the half-life of the reaction.

N_2(g)+3H_2(g)=2NH_3(g) What is the rate of disappearance of N_2 and H_2 is the rate of formation be 0.56 mol L^-1 s^-1 . Show that infinite time required for completion of 1st order reaction.

For a first order reaction , show that time required for 99% completion is twice the time required for the completion of 90% of reaction.

25% of a first order reaction is completed in 30 min . Find the time required for completion of 50% of the reaction.
