Explanation / Answer

Answer

Question 26- The option (a) is correct. Atomic number.

Explanation - Because atomic number defined many properties of element.when atomic number increase and decrease there variation in properties and chemical nature of elements.

Question 27 - The option (c) is correct. The energy of reactant and product change.

Explanation - As the activation energy lower enthalpy of products will be increase. It favour the forward reaction.

Question 28 - The option (b) is correct .?G is change in free energy.

Explanation -G is state function which denoted energy function . We can not measure all the change in free energy. So that we can measure change in free energy.

Question 29 - The option (b) is correct. Decrease ?G.

Explanation - The reaction in which ?G is decrease energetically favourable because the reaction proceed in direction of increase entropy and decrease ?G.

Question 30- the option (c) is correct. Starch

Explanation - Because when plant have extra sugar so plant store glucose in form of starch. Starch is a polymeric form of glucose.
