The unit of rate constant for a first-order reaction is

\(A \rightarrow B\) is a first order reaction. What is the concentration of reactant A after 28.8 seconds if the initial concentration of A is 0.1 M and rate constant \(k = 0.0693\,s^{-1}\)? (Given \(e = 2.718\))

The rate of disappearance of hydrogen \((\text{H}_2)\) from the reaction \[ \text{N}_2(g) + 3\text{H}_2(g) \rightarrow 2\text{NH}_3(g) \] is \(6\, \text{g L}^{-1}\text{s}^{-1}\). The rate of production of ammonia \((\text{NH}_3)\) in \(\text{g L}^{-1}\text{s}^{-1}\) is:

\(P \rightarrow Q\) is a zero order reaction. If the concentration of \(P\) decreases from \(0.1\ M\) to \(0.05\ M\) in 10 seconds, then the concentration of \(P\) after 15 seconds is
