When conducting chemical reactions in the lab or in industrial processes, it can be important to know whether a reaction has reached equilibrium. By measuring the reaction quotient, QQQ, of a chemical reaction and comparing it to the equilibrium constant, KKK, we can identify whether a reaction is at equilibrium. For the reaction aA+bB⇌cC+dDaA+bB⇌cC+dD the reaction quotient, QQQ, is given by the expression Q=[C]c[D]d[A]a[B]bQ=[C]c[D]d[A]a[B]b under any conditions. The value of QQQ is equal to KKK only at equilibrium. he following reaction was carried out in a 2.50 LL reaction vessel at 1100 KK: C(s)+H2O(g)⇌CO(g)+H2(g)C(s)+H2O(g)⇌CO(g)+H2(g) If during the course of the reaction, the vessel is found to contain 6.25 molmol of CC, 15.2 molmol of H2OH2O, 4.00 molmol of COCO, and 7.10 molmol of H2H2, what is the reaction quotient QQQ? Enter the reaction quotient numerically.
When conducting
For the reaction
aA+bB⇌cC+dDaA+bB⇌cC+dD
the reaction quotient, QQQ, is given by the expression
Q=[C]c[D]d[A]a[B]bQ=[C]c[D]d[A]a[B]b
under any conditions. The value of QQQ is equal to KKK only at equilibrium.
he following reaction was carried out in a 2.50 LL reaction vessel at 1100 KK:
C(s)+H2O(g)⇌CO(g)+H2(g)C(s)+H2O(g)⇌CO(g)+H2(g)
If during the course of the reaction, the vessel is found to contain 6.25 molmol of CC, 15.2 molmol of H2OH2O, 4.00 molmol of COCO, and 7.10 molmol of H2H2, what is the reaction quotient QQQ?
