I'd say that it will shift to the left because HCl will provide additional H+ ions which are present on the right side of the equation. Higher concentration of reagents on the one side - chemical equilibrium moves to the opposite side (le chatelier's principle)

The reaction a(g)⇌b(g) has an equilibrium constant of 5.8 and under certain conditions has q = 336. part a what can you conclude

Vika [28.1K]

Answer:

The answer is "As $Q=336$ , at high-temperature $\Delta G_{rxn}>0$ and When $K>1,$ $\Delta G^{\circ}_{rxn}>0$ ."

Explanation:

The equation for the reaction is:

$A(g) \leftrightharpoons B(g)$

$K=5.8\\\\Q=336$

At equilibrium,

$\Delta G^{\circ}_{rxn}>0$ $=-RT \ln \ K$

When k=5.8(>1), the value of $\ln k$ would be positive

So, $\Delta G^{\circ}_{rxn}$ is negative (< 0)

So if K > l, $\Delta G^{\circ}_{rxn}$

If the reaction is not in equilibrium so the equation is :

$\Delta G_{rxn}>0$ = $\Delta G^{\circ}_{rxn}$ $+RT \ln Q$

Substituting the expression:

$\Delta G_{rxn}>0$ $= (-RT \ln K) + RT \ln Q$

$= RT(\ln Q- \ln K)\\= RT(\ln (336)-\ln (5.8))\\= RT(4.06)$

It is the positive value for all temperatures.

So, As Q = 336, at the high temperature $\Delta G_{rxn}>0$ .

By titration, it is found that 28.5 mL of 0.183 M NaOH(aq) is needed to neutralize 25.0 mL of HCl(aq). Calculate the

maksim [4K]

Answer:

0.209M

Explanation:

M1V1=M2V2

(28.5 mL)(0.183M)=(25.0mL)(M)

M2= 0.209M

The most stable conformation of trans-1-tert-butyl-2-methylcyclohexane is the one in which:

Margaret [11]

The most stable conformation of trans-1-tert-butyl-2-methylcyclohexane is the one in which both the tert-butyl group and the methyl group are located near the equatorial position. Trans conformation are usually stable at the equatorial position to avoid the bulkyl group ( the tert-butyl group and methyl group) be together to reduce the so called Steric hindrance.
