Areaction 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?
a it increased the number of molecular collisions.
b it decreased the number of molecular collisions.
c it decreased the space between the molecules and lowered the reaction rate.
d it increased the space between the molecules and increased the reaction rate.
