Q1ChemistryUnit 4: Chemical Thermodynamics
The plot shows the variation of −ln⁡Kp-\ln \boldsymbol{K}_{\boldsymbol{p}} versus temperature for the two reactions. M(s)+12O2(g)→MO(s)M(s)+\frac{1}{2} O_{2}(g) \rightarrow M O(s) and C(s)+12O2(g)→CO(s)C(s)+\frac{1}{2} O_{2}(g) \rightarrow C O(s) Identify the correct statement?
Q2ChemistryUnit 4: Chemical Thermodynamics
An ideal gas is compressed in a closed container its U?
Q3ChemistryUnit 4: Chemical Thermodynamics
A system is said to be in thermodynamic equilibrium with Surrounding ¡f
Q4ChemistryUnit 4: Chemical Thermodynamics
Assertion The change in internal energy and change in heat enthalpy does not depend upon the path by which changes are brought in. Reason Both ΔU\Delta U and ΔH\Delta H are path independent as U and H are state functions.
Q5ChemistryUnit 4: Chemical Thermodynamics
For a given reaction, H2O(l)⇌\boldsymbol{H}_{2} \boldsymbol{O}(l) \rightleftharpoons H2O(s)at0∘CH_{2} O(s) a t 0^{\circ} C and 1 bar, which of the following is true?
Q6ChemistryUnit 4: Chemical Thermodynamics
Assertion Adsorption is exothermic and spontaneous inspite of the fact that adsorption is accompained with decrease in entropy. Reason The factor TΔST \Delta S is lesser than ΔH\Delta H
Q7ChemistryUnit 4: Chemical Thermodynamics
When fuel is added to the exhaust (burnt) gases in a jet engine combustion takes place. Some facts are mentioned here about this combustion. Pick the false one?
Q8ChemistryUnit 4: Chemical Thermodynamics
Which of the following equations corresponds to the definition of enthalpy of formation at 298K?298 K ?
