- 下列四个原电池中，其电池反应不为 H2(2pθ)→H2(pθ) 的电池是： A: Pt,H2(2pθ)|H+(a= 0.1)||H+(a= 0.2)|H2(pθ),Pt B: Pt,H2(2pθ)|H+(a= 10-8)|H2(pθ),Pt C: Pt,H2(2pθ)|H+(a= 0.1)|H2(pθ),Pt D: Pt,H2(2pθ)|H+(a = 0.1)||KCl(m = 1)|Hg2Cl2(s),Hg－Hg,Hg2Cl2(s)|KCl(m = 1)|H+(a = 0.1)|H2(pθ),Pt
- Using the notation Pt to designate this period's price level and Pt-1 to designate last period's price level, the formula for measuring the inflation rate from last period to this period is A: [(Pt - Pt - 1) / Pt] × 100. B: [(Pt -1 - Pt) / Pt - 1] × 100. C: [(Pt - Pt - 1) / Pt - 1] × 100. D: [(Pt -1 - Pt) / Pt] × 100.
