D. A substance that has no E. ffect on a reaction. 相关知识点: 试题来源: 解析 C。解析:文中提到“A catalyst is a substance that increases the rate of a reaction without being consumed in the process”,即催化剂是一种在反应过程中不被消耗却能提高反应速率的物质。反馈 收藏 ...
A catalyst is a substance that works to accelerate a chemical reaction. Without the help of a catalyst, a reaction might...

a "catalyst for political change"). A promoter is an accelerator of catalysis but not a catalyst by itself. An inhibitor inhibits the working of a catalyst. History The phrase catalysis was coined by Jöns Jakob Berzelius in 1835 who was the first to note that certain ...

When a catalyst is added to a reaction at equilibrium, what happens to the equilibrium position? A. Shifts to the right B. Shifts to the left C. No change D. Can't determine 相关知识点: 试题来源: 解析 C。解析:催化剂只能改变反应速率,不能改变平衡状态,所以平衡位置不变。
The additive contains nanoparticles of titanium dioxide which act as a catalyst (触媒剂;催化剂). When light hits these particles, they react with oxygen to make what is essentially a peroxide(过氧化物) bleach. This in turn reacts with air 3 such as nitric oxide and breaks them down. ...
