What type of reaction is represented in the following example?
2c2h4o(g) + 5o2 (g) 4co2 (g) + 4h2o (l) δh = -2385 kj
exothermic
endothermic

Explanation:

A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.  

For example,

The value of = +ve for endothermic reaction.

Whereas a chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.  

For example, is an exothermic reaction.

The value of = -ve for exothermic reaction.

Also, the given reaction,          

It is also an exothermic reaction because heat is releasing as value of is negative.

Thus, we can conclude that the given reaction is exothermic in nature.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
