Which heat is produced throughout the conducting wire?

The value of $$\triangle $$H and $$\triangle $$S for the reaction, $${ C }_{ \left( graphite \right)  }+{ CO }_{ 2\left( g \right)  }\rightarrow 2{ CO }_{ (g) }$$ are 170kJ  and $${ 170JK }^{ -1 }$$, respectively. This reaction will be spontaneous  at:

For an exothermic reaction to be sponteneous:

For a reversible spontaneous change $$\triangle s$$ is:

For a process to be spontaneous at constant $$T$$ and $$P$$:

Which of the following must be spontaneous at all temperatures?

Specific heats of monoatomic and diatomic gases are same and
satisfy the relation which is

$$Pt$$ | $$Cl_2$$ ($$P_1$$ atm) | $$HCl$$ ($$0.1$$M) | $$Cl_2$$ ($$P_2$$ atm) | $$Pt$$, cell reaction will be spontaneous if:

In the series $$Sc(Z=21)$$ to $$Zn(Z=30)$$, the enthalpy of atomisation of which element is least?

For a first order reaction rate constant is $$1 \times {10^{ - 5}}{\sec ^{ - 1}}$$ having $${E_a} = 1800\ kJ/mol$$ . Then the value of $$\ell nA$$ at$$T = 600\ K$$ is:-
