Reducing: Mg is a reducing agent, N 2 is an oxidizing agent.
For the reaction c2h6 (g) → c2h4 (g) + h2 (g) δh° is +137 kj/mol and δs° is +120 j/k ∙ mol. This reaction is <span>spontaneous only at high temperature.
here the values of </span>δh° is +137 kj/mol and δs° is +120 kj/mol. so, both the value are wit the sign "+". when both values are positive than the reaction is not spontaneous at low temperature, the reaction is spontaneous only at high temperature.
The relation between T1 and T2 is T1= T2.
when 200 mL are mixed so, we will have twice the number of moles of water
and twice as much heat will be released this has to heat twice of the mass of the
water, so the temperature rises as the same
