A)
B)
C)
D)
Correct Answer: A
Solution :
For the reaction, CaCO3(g) ⇌ CaO(s) + CO2(g) Kp = \[{{P}_{C{{O}_{2}}}}\] and KC = [CO2] (Q [CaCO3] = 1 and [CaO] = 1 for solids] According to Arrhenius equation we have \[K=A{{e}^{-\Delta H{{{}^\circ }_{r}}/RT}}\] Taking logarithm, we have \[\log {{K}_{p}}=\log A-\frac{\Delta H_{r}^{o}}{RT(2.303)}\] This is an equation of straight line. When log Kp is plotted against 1 / T. we get a straight line.You need to login to perform this action.
