Consider this system at equilibrium. A(aq)↽−−⇀B(aq)ΔH=+350 kJ/mol What can be said about Q and K immediately after an increase in temperature? Q < K because Q decreased. Q < K because K increased. Q > K because Q increased. Q > K because K decreased. Q = K because neither changed. How will the system respond to a temperature increase?

A.) Q < K because Q decreased

B. shift right

Explanation:

Reactant>Products

K = Product/Reactant

An endothermic reffers to any reaction which absorbs energy from its surroundings, usually in the form of heat.

ΔH. In endothermic reactions, K increases when Temperature increases.

The given reaction is an endothermic reaction, and in an endothermic reaction, when there is increase in temperature, the product side is more favored. The system will shifts to the right side of the reaction. Q < K then K is constant and Q is decreased.then Q < K because Q decreased

The system respond to a temperature increase by shifting to the right

d

explanation:

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.
