$Mn{O_2} + 4HCl \to MnC{l_2} + 2{H_2}O + C{l_2}$
$(1)$ Manganese ion is oxidised
$(2)$ Manganese ion is reduced
$(3)$ Chloride ion is oxidised
$(4)$Chloride ion is reduced.
Which of these statements are correct
$\Delta {U_{BC}} = - 5\,kJ\,mo{l^{ - 1}},{q_{AB}} = 2\,kJ\,mo{l^{ - 1}}$
$\Delta {W_{AB}} = - 5\,kJ\,mo{l^{ - 1}},{W_{CA}} = 3\,kJ\,mo{l^{ - 1}}$
Heat absorbed by the system during process $CA$ is......$kJ\,mo{l^{ - 1}}$
