Question

In which of the following equations, the enthalpy change will represent $\Delta H^0_f$ of $N_2H_{4(l)}$ with sign reversed?
(a) $N_{2(g)} + 2H_{2(g)} \rightarrow N_2H_{4(g)}$
(b) $2N_{(g)} + 4H_{(g)} \rightarrow N_2H_{4(l)}$
(c) $N_2H_{4(l)} \rightarrow 2N_{(g)} + 4H_{(g)}$
(d) $N_2H_{4(g)} \rightarrow N_{2(g)} + 2H_{2(g)}$
