For a reaction type \(A + B \rightarrow\) products, it is observed that doubling concentration of \(A\) causes the reaction rate to be four times as great, but doubling amount of \(B\) does not affect the rate. The unit of rate constant is

A chemical reaction was carried out at \(320\,K\) and \(300\,K\). The rate constants were found to be \(k_1\) and \(k_2\) respectively. Then

For the reaction,
\[ 2A(g) + B_2(g) \rightleftharpoons 2AB_2(g) \] the equilibrium constant, \(K_p\) at \(300\,K\) is \(16.0\). The value of \(K_p\) for \(AB_2(g) \rightleftharpoons A(g) + \dfrac{1}{2}B_2(g)\) is

The standard Gibbs free energy change, \(\Delta G^\circ\) is related to equilibrium constant, \(K_p\), as
