Different reactions need different catalysts. A catalyst that works well for one reaction is added to a second, unrelated reaction. What is the most likely result?
The second reaction gives a larger yield of product
The second reaction runs at the same rate as before
The second reaction runs much faster than before
The second reaction stops before it is complete
