Question
Riddle me this: X and Y react to create Z. The initial concentration of X is 9M, Y starts at 4M, Z starts at 1M.
Riddle me this: X and Y react to create Z. The initial concentration of X is 9M, Y starts at 4M, Z starts at 1M. After 10 minutes, the concentration of X is 3M and Y is 2.5M, with Z now being at 4M. Doubling the concentration of X and keeping Y the same, the rate was 9 times as fast as it was before. Doubling Y but keeping X the same made it go at the same rate. (Pssst - a table works well to see the patterns)
