The equation that is incorrect is [JEE Main 2020, 7 Jan (Shift 2)]

\(\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaBr}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaCl}}=\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{KBr}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{KCl}}\)

\(\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{H}_{2} \mathrm{O}}=\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{HCl}}+\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaOH}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaCl}}\)

\(\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaBr}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaI}}=\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{KBr}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaBr}}\)

\(\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{KCl}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaCl}}=\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{KBr}}-\left(\Lambda_{\mathrm{m}}^{\circ}\right)_{\mathrm{NaBr}}\)
