Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of an enzyme is to increase the rate

Accounting rate of return The accounting rate of return (ARR) is a way of comparing the profits you expect to make from an investment to the amount you need to invest.

For example‚ if a project requires an average investment of £100‚000 and is expected to produce an average annual profit of £15‚000‚ the ARR would be 15 per cent. The

(Interest rate parity is a no-arbitrage condition representing an equilibrium state under which investors will be indifferent to interest rates available on bank deposits in two countries.[1] The fact that this condition does not always hold allows for potential opportunities to earn riskless profits from covered interest arbitrage. Two assumptions central to interest rate parity are capital mobility and perfect substitutability of domestic and foreign assets. Given foreign exchange market equilibrium

Floating Exchange Rate Exchange rates between currencies have been highly unstable since the collapse of the Bretton Woods system of fixed exchange rates‚ which lasted from 1946 to 1973. Under the "floating" exchange rates‚ since 1973‚ exchange rates are determined by people buying and selling currencies in the foreign-exchange markets . The instability of floating rates has surprised and disappointed many economists and businessmen‚ who had not expected them to create so much uncertainty.
