For the chemical equilibrium, 
⇌ 
can be determined from which one of the following plots
Text Solution
Verified by ExpertsA
For the reaction,
CaCO 3( g ) ⇌ CaO ( s ) + CO 2( g )
K p = 
and K C = [ CO 2 ]
( Q [ CaCO 3 ] = 1 and [ CaO ] = 1 for solids]
According to Arrhenius equation we have
Taking logarithm, we have
This is an equation of straight line. When log K p is plotted against 1 / T . we get a straight line.
The intercept of this line = log A , slope = –∆ H ° r / 2.303 R
Knowing the value of slope from the plot and universal gas constant R , ∆ H r ° can be calculated.
(Equation of straight line : Y = mx + C. Here,
Y m x C
