The literature melting point of compound A is known to be at 54-55 °C. If a very small amount of Compound B, whose melting point is 81-82 °C, is mixed in with the Compound A, what would be expected to happen to the melting point of the mixture? a. The melting point would be slightly higher than 55 °C. b. The melting point would not be affected. c. The melting point would be a weighted average of the two melting points. d. The melting point would be slightly lower than 55 °C e. The effect on the melting point cannot be predicted.
