$(A)$ Stereochemistry of addition - SYN ONLY
$(B)$ Regiochemistry of addition- ANTI-MARKOVNIKOV OR ANTI-MARKOVNIKOV LIKE
$Sn{O_2}(s) + 2{H_2}\left( g \right) \rightleftharpoons 2{H_2}O\left( g \right) + Sn\left( l \right)$
At equilibrium, the mixture of steam and hydrogen contains $40\%$ $H_2$ by volume then find $K_p$ for the reaction
$MgO(s) + C(s) \to Mg(s) + CO(g)$, for which $\Delta _r{H^o} = + 491.1\,kJ\,mo{l^{ - 1}}$ and $\Delta _r{S^o} = 198.0\,Jk^{-1}\,mo{l^{ - 1}}$ is not feasible at $298\, K$. Temperature above which reaction will be feasible is.....$K$
