Work Step by Step

The first reaction is impossible. Conservation of strangeness is violated: $-2 \neq -1 + 0$. Conservation of energy is violated: $$13149 MeV/c^2 \gt 1189.4 MeV/c^2+139.6 MeV/c^2$$ The second reaction is impossible. Conservation of strangeness is violated: $-3 \neq -1 + 0 + 0$. Conservation of lepton number is violated: $0 \neq 0 + 0 + 1$. Conservation of spin is violated: $\frac{3}{2} \neq \frac{1}{2} + 0 + \frac{1}{2}$. The third reaction is possible. No conservation principles are violated.
