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 WhenK>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.

Answer:

Protons, neutrons, and electrons

Explanation:

Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
