Question: Hello. Could someone break this solution down a bit? In the prediction (second photo), why did 3 x 10^-2 turn into 1/3 x 10^2 ?

Hello. Could someone break this solution down a bit? In the prediction (second photo), why did 3 x 10^-2 turn into 1/3 x 10^2 ? Why did the exponent turn into a positive?

41. For the following balanced reaction, Keq=0.03M. What is the Kwq of the reverse reaction? PCl3+PCl3+Cl2 A. K6e=1.0101M1 B. Koq=1.0102Me1 C. Kma=3.0102M1 D. Kwil=3.3=102M1 E. Keq=3.3101M1 Think: The Ke4 for a balanced reaction is given, and question asks for the Keaf for the reverse reaction. This will be the inverse of the Keq for the forward reaction. for the forward reaction: xsa=[PCH5][PCl1][Cl2]=0.03M Foe the rewerse reaction: +1=[PCCj][C3][PCl6]=0.051M1 Predict: Take the inverse of 0.03M, which lis: 301=31021=31102=0.331023.3102M1 Match: Answer choige (t) matdies the prediction
