_?Dear Student,
Given : Kp= 1.64 atm , T=1000 K , V=10L , initial weight of CaCO_?3? =50g

number of moles of CaCO₃=

\frac{50}{100}

=0.5 moles
initial concentration of CaCO₃=

\frac{0.5}{10} = 0.05

C a C O_{3} (s) ⇌ C a O (s) + C O_{2}

?initial 0.05 0 0
equilibrium 0.05-x x x
Kp=pCO_?2?
1.64 =

x \times 0.0821 \times 1000

x=0.0199

≃

0.2 moles
unreacted CO₂=0.5-0.2 =0.3 moles
% of unreacted CO₂=

\frac{u n r e a c t e d}{i n i t i a l} \times 100

\frac{0.3}{0.5} \times 100

= 60%
