mora measures the speed of the particles in a solid mass. she wants to speed up the action. which action will allow her to do so?\nadding more mass\nbreaking it apart\nusing an inhibitor\nlowering the activation energy
Answer
Brief Explanations:
Adding more mass doesn't speed up particle - action. Breaking it apart doesn't directly speed up particle action. Using an inhibitor slows down reactions. Lowering the activation energy allows particles to react more quickly, thus speeding up the action.
Answer:
lowering the activation energy
