Which is True $(T)$ and False $(F)$ of the following statements?
$1.$ By catalyst,the forward reaction becomes fast and the reverse reaction becomes slow.
$2.$ $A$ catalyst decreases the potential energy of reactants and products.
$3.$ $A$ catalyst forms bonds in the reaction,so it is consumed.

Platinized asbestos is used as a catalyst in the manufacture of $H_2SO_4$. It is an example of

Catalysts in the following reactions are:
$(I) CH_3COOCH_{3(l)} + H_2O_{(l)} \rightarrow CH_3COOH_{(aq)} + CH_3OH_{(l)}$
$(II) 2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$ (Contact Process)
$(III) 2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$ (Lead Chamber Process)
$(IV) N_{2(g)} + 3H_{2(g)} \rightarrow 2NH_{3(g)}$ (Haber Process)
