The partial pressure of \[C{{H}_{3}}OH(g),CO(g)\] and \[{{H}_{2}}(g)\] in equilibrium mixture for the reaction, \[CO(g)+2{{H}_{2}}(g)\rightleftharpoons C{{H}_{3}}OH(g)\] are 2.0, 1.0 and 0.1 atm respectively at \[427{}^\circ C\]. The value of \[{{K}_{p}}\] for the decomposition of \[C{{H}_{3}}OH\] to CO and \[{{H}_{2}}\] is

• A. \[{{10}^{2}}atm\]
• B. \[2\times {{10}^{2}}at{{m}^{-1}}\]
• C. \[50\text{ }at{{m}^{2}}\]
• D. \[5\times {{10}^{-3}}at{{m}^{2}}\]
