MCQ
In an isochoric process the increase in internal energy is
  • ✓
    Equal to the heat absorbed
  • B
    Equal to the heat evolved
  • C
    Equal to the work done
  • D
    Equal to the sum of the heat absorbed and work done
✓

Answer

Correct option: A.
Equal to the heat absorbed
(a)For isochoric process $\Delta V = 0$ so ${q_v} = \Delta E$ i.e. heat given to a system under constant volume is used up in increasing $\Delta E$.

For reaction :

$2NO_2(g) + O_3(g) \to N_2O_5(g) + O_2(g)$

rate law is $R = K\, [NO_2]' [O_3]'$.

Which of these possible reaction mechanisms is consistent with the rate law?

Mechanism $I :$

$NO_2(g) + O_3(g) \to NO_3(g) + O_2(g)$ (slow)

$NO_3(g) + NO_2(g) \to N_2O_5(g)$ (fast)

Mechanism $II :$

$O_3(g)  \rightleftharpoons  O_2(g) + [O]$ (fast)

$NO_2(g) + [O] \to NO_3$ (slow)

$NO_3(g) + NO_2(g) \to  N_2O_5$ (fast)
