A reaction occurs when solid X is placed into solution Y. As a result, the temperature of the new solution increases by 3°C.
The temperature rises another 2°C when more of solid X is added to the solution. What does this indicate about the effect of
adding more solid?
It increased the number of molecular collisions,
It decreased the number of molecular collisions.
It decreased the space between the molecules and lowered the reaction rate.
It increased the space between the molecules and increased the reaction rate.
