Question

Evaluate a uniform pseudo-first-order gas decomposition defined broadly by the stoichiometric reaction $A(g) \rightarrow B(g) + 2C(g)$ inside a perfectly sealed, constant-volume chamber. Assuming the sole starting gas is $A$ with baseline pressure $P_0$, and the compound total pressure continuously reads $P_t$, which of the specified relations accurately portray the internal kinetic reality?

Prashant Kotian · Accepted Answer

Correct answer: A,B,C. Tracking stoichiometry: , isolating . Thus . This makes A correct, and B follows correctly directly plugging into . C is true as 1 mole gas gives 3 total moles, so ending pressure triples . D is false because product pressure is uniquely , which rigorously evaluates to , not merely .
