The decomposition of nh4hs is endothermic: nh4hs(s)⇌nh3(g)+h2s(g) part a which change to an equilibrium mixture of this reaction results in the formation of more h2s? which change to an equilibrium mixture of this reaction results in the formation of more ? a decrease in the volume of the reaction vessel (at constant temperature) an increase in the amount of nh4hs in the reaction vessel an increase in temperature all of the above

Explanation:

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.

As the given reaction is as follows.

(a)  When increase the temperature of the reactants or system then equilibrium will shift in forward direction where there is less temperature. It is possible for an endothermic reaction.

Thus, formation of will increase.

Hence, formation of will decrease with decrease in volume.

Thus, we can conclude that formation of will increase then.

12 is it do you think so

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
