Question

Given the following reaction:
CH3CH2OH(l)+3O2(g)→2CO2(g)+3H2O(l)CH3CH2OH(l)+3O2(g)→2CO2(g)+3H2O(l)

∆H = –2200 kJ/mol CH3CH2OHCH3CH2OH

c) If you add heat to the system, which of the following will occur? Check all that apply.

Select one or more:

a. the reaction will shift left

b. the reaction will shift right

c. [CH3CH2OHCH3CH2OH] will increase

d. [H2OH2O] will decrease

e. [O2O2] will decrease

f. [CO2CO2] will increase

Answer 1

given reaction.. CH CH₂OH(1) +30₂(g) 200₂(g) + 3 H₂Ol) and AH = –2200 kJ/mol so as AH is negative it means it is aan exothermic reaction , le ho it Defects heat.. According to Le Chatelienis principle the a system unders equillibrium shifte itself in such way that in any change in pressure, temperature on concentration gets. neutralise so herre as we aeld the heat go the equillibrium will try to shift. in that direction in which heat will get absorbed so the backward reaction which is an endothermie process on will take place in greater extent than the forward preaction and hence the equillibrium will shift tow ares left. So option is conmeet. so as for wand weation is I p y

o so as backward peachon is more than .. for wand reaction so concentration of product will decrease omel concentration of penetant will increase 50 [H₂o] will decrease [ CH₂ CH₂OH.] will increase. [co] will decrease and [ 2] will increase are also so option ® and @ connect.
