Answer:
- 1.22KJ
Explanation:
First we put down the equation of the reaction;
NH4Cl(s)<-------->NH3(g) + HCl(g)
The equilibrium constant K is obtained from;
K= P(NH3) × P(HCl)
Where;
P(NH3)= pressure of ammonia
P(HCl)= pressure of hydrogen chloride gas
Pure solids and liquids are not included in the equilibrium constant expression. This is because they do not affect the reactant amount at equilibrium in the reaction, so they are disregarded and kept at 1. Remember that the activity, a, of any solid or liquid in a reaction is equal to 1. Hence [NH4Cl]= 1
K= 1.03 × 1.18 = 1.22
∆G° = -RTlnK
R= 8.314 JK-1mol-1
T= 465°C +273= 738K
K= 1.22
lnK= ln(1.22)= 0.19885
∆G= -(8.314 ×738 ×0.19885)
∆G= -1220.1 J
∆G= -1.22×10^3 J
∆G= - 1.22KJ

Answer:
Carbon dioxide is an atmospheric constituent that plays several vital roles in the environment. It is a greenhouse gas that traps infrared radiation heat in the atmosphere. It plays a crucial role in the weathering of rocks. ... It is stored in biomass, organic matter in sediments, and in carbonate rocks like limestone.
Explanation:
The purpose of the SN1 and SN2 reactions are;
To study the effect of substrate structure and leaving groups on the sn1/sn2 reactions.
To compare the different mechanisms of nucleophilic substitution (SN) reactions.
<h3>What is nucleophilic reaction?</h3>
We know that in the reaction between an alkyl halide and a specie that has a high electron density, the reaction would involve the attack of a center that has a developing positive charge. The specie that attacks the center taht has the positive charge is called the nucleophile.
We know that the shape of the substrate alkyl halide affects the rate of the reaction or the nature of the nucleophilic reaction. The tertiary alkyl halides tend to undergo the reaction via the SN1 mechanism while the primary alkyl halides tend to undergo the reaction via the SN2 mechanim. The mechanism of the secondary alkyl halides would depend on the conditions of the reaction.
