Select the correct statement (s)
(a) When \( \mathrm{T} \rightarrow \infty \) or \( \mathrm{E}_{\mathrm{a}} \rightarrow 0 \mathrm{k}=\mathrm{A} \)
(b) A positive catalyst can change \( \Delta \mathrm{H} \) of the reaction
(c) A mixture of reactants may be thermodynamically unstable but kinetically stable
(d) A negative catalyst increases the activation energy of the reaction
