To determine the sign of ΔH for the reaction \( H_2(g) \rightarrow 2H(g) \), we can follow these steps: ### Step 1: Understand the Reaction The reaction involves the dissociation of molecular hydrogen (\( H_2 \)) into two hydrogen atoms (\( 2H \)). This process involves breaking a bond in the \( H_2 \) molecule. **Hint:** Remember that breaking bonds typically requires energy. ### Step 2: Analyze Bond Breaking ...
