In this reaction, the solvent and electrolyte is water, and they are driven by the formation of the non-electrolytic product. Therefore, the driving force behind the neutralization reaction between HCl and NaOH is the formation of sodium chloride, NaCl.
What is Opposing Force in chemistry?
The opposing force is that which leads it in the reverse direction. The greater the difference between these forces, the farther from equilibrium the system will be, and the process will generally happen faster and more violently. This also means a less reversible process.
What are irreversible thermodynamic processes?
An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in. The irreversibility of any natural process results from the second law of thermodynamics.
What happens when curd is set is it a reversible change explain?
Whereas curdling of milk is an irreversible change because on curdling, milk changes to curd and cream, and gets spoilt when not refrigerated, and cannot be changed back to milk by any process.
Which bacteria helps in setting of curd?
The preparation of curd requires a lactobacillus bacteria, while yogurt is made using two specific strains of bacteria called Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus bacteria. Other strains of lactic acid bacteria may also be added.
How does the curd set?
Ans: A small quantity of curd is added to warm milk. The milk is stirred and is set aside undisturbed for a few hours at a warm place. Curd formed from milk cannot be changed into milk again. So, this an irreversible (cannot be reversed) change.
Which is better curd or yogurt?
