A block of zinc has an initial temperature of 94.2 degrees celcius and is immererd in 105 g of water at 21.90 degrees celcius. At thermal equilibrium, the final temperature is 25.20 degrees celcius. What is the mass of the zinc block? Cs(Zn) = 0.390 J/gxdegrees celcius Cs(H2O) = 4.18 J/gx degrees celcus
Potential Energy (kJ)
1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction.
AH = -950 kJ
AH = 575 kJ
(i) Cl₂ (g) + Pt (s) 2C1 (g) + Pt (s)
Ea = 1550 kJ
(ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s)
(iii) Cl (g) + CICO (g) → Cl₂CO (g)
Ea = 2240 kJ
Ea = 2350 kJ
AH = -825 kJ
