Question
Which of the following is an exception to octet rule of configuration? a) HCI b) HNO3 c) H2SO4 d) H3PO4. Which of the following statements regarding the effect of a temperature change on the equilibrium of a reaction is true? a) For an exothermic reaction, increasing temperature causes the reaction to shift right. b) For an exothermic reaction, increasing temperature causes the reaction to shift left. c) For both exothermic and endothermic reactions, increasing temperature does not affect the equilibrium. d) For an endothermic reaction, increasing temperature causes the reaction to shift left.Explanation / Answer
Ans 3 -Option b) is correct because hest is released if we take the heat the equllibrium shifts towards left.This is because of Le Chatelier's principle . example can be taken to under stand better of Ca(OH)2.
