0.75 mole of solid X 4 and 2 mole of O 2 are heated to completely react in a closed rigid container to form only one gaseous compound (no reactant left behind). Find the ratio of final pressure at 327ºC to the initial pressure at 27ºC in the flask. Fill your answer as x, where ratio is x : 1.
Text Solution
Verified by ExpertsThe correct answer is:
1
(1 )
Mole atoms of X = 0.75 × 4 = 3
Mole atoms of O = 2 × 2 = 4
Hence the product is X 3 O 4 (g)
Initial moles of gaseous reactants, n 1 = 2 (oxygen only)
Final moles of gaseous product, n 2 = 1 (X 3 O 4 )
Hence, 
= 
= 
= 1 or P 2 : P 1 : 1 : 1
